IMMERSIBLE SAR PROBE CALIBRATION REPORT Part Number: IXP – 050 S/N 0082 March 2002 Indexsar Limited Oakfield House Cudworth Lane Newdigate Surrey RH5 5DR Tel: +44 (0) 1306 631 233 Fax: +44 (0) 1306 631 834 e-mail: [email protected] 2 INTRODUCTION This Report presents measured calibration data for a particular Indexsar SAR probe (S/N 0082) and describes the procedures used for characterisation and calibration. Indexsar probes are characterised using procedures that, where applicable, follow the recommendations of CENELEC [1] and IEEE [2] standards. The procedures incorporate techniques for probe linearisation, isotropy assessment and determination of liquid factors. Calibrations are determined by comparing probe readings with theoretical computations in canonical test geometries, using normalised power inputs. Each step of the calibration procedure and the equipment used is described in the sections below. CALIBRATION PROCEDURE 1. Equipment Used For the first part of the calibration procedure, the probe is placed in a calibration jig as pictured in Figure 1. In this position the probe can be rotated about its axis by a belt driven by a stepper motor. The probe is attached to an amplifier that is connected via an optical cable to a PC. A schematic representation of the test geometry is illustrated in Figure 2. A balanced dipole (900 or 1800 MHz) is inserted horizontally into the bracket attached to a second belt (Figure 1). The dipole also can be rotated about its axis. A cable connects the dipole to a signal generator, via a coupler and power meter. The signal generator is used to output a signal of 900 (or 1800) MHz at constant power, which is monitored on the power meter. The probe is positioned so that its sensors line up with the rotation center of the dipole. By recording E-field measurements as both the probe and the dipole are rotated, the spherical isotropy of the probe can be determined. The calibration process requires E-field measurements to be taken in air, in 900 MHz simulated brain liquid and in 1800 MHz simulated brain liquid. When it is necessary to place the probe in liquid, a rectangular box made from PMMA (200mm internal width, 200mm internal height and 100mm internal depth; wall thickness 4mm) is filled with the appropriate liquid and positioned on the stand so that the probe tip is centered within the liquid (Figure 1). The box is positioned so that its outer surface is 2mm from the dipole. 2. Linearising probe output The probe channel output signals are linearised in the manner set out in Refs [1] and [2]. The following equation is utilized for each channel: U lin = U o/p + U o/p 2 / DCP(1) 3 where U lin is the linearised signal, U o/p is the raw output signal in voltage units and DCP is the diode compression potential in similar voltage units. DCP is determined from fitting equation (1) to measurements of U lin versus source feed power over the full dynamic range of the probe. The DCP is a characteristic of the schottky diodes used as the sensors. For the IXP-050 probes the DCP values are typically 0.10V (or 20 in the voltage units used by Indexsar software, which are V*200). 3. Optimizing channel sensitivity factors in air The first step of the calibration process is to calibrate the Indexsar probe to a W&G EMR300 E-field meter in air. The principal reasons for this are to balance the channels in air and to obtain air factors that are used in subsequent steps of the calibration procedure. The probe and a 900 MHz standard dipole are positioned in the calibration jig as outlined in the section above. With the Indexsar probe located in air, individual channel output voltages are recorded as probe and dipole are rotated. An ‘air factor’ is applied to each of the probe’s three channels in order to equilibrate the peak magnitudes of each channel. A multiplier is applied to factors to bring the magnitudes of the average E-field measurements as close as possible to those of the W&G probe. The following equation is used (where output voltages are in units of V*200): E air 2 (V/m) = U linx * Air Factor x + U liny * Air Factor y + U linz * Air Factor z (2) It should be noted that the IXP-050 probes are optimised for use in t issue simulating liquids and do not behave isotropically in air. 4. 900 MHz Liquid Calibration The second phase of calibration requires the channel output voltages of the Indexsar probe to be measured in a box filled with 900 MHz simulated brain liquid. The box of liquid is placed on the stand as described above and as pictured in Figure 1. Channel outputs for the different orientations of probe and dipole are recorded and entered into a spreadsheet. These measurements are multiplied by the previously determined air factors. Another factor, referred to as the ‘liquid factor’ is also applied to the measurements of each channel. The magnitude of the liquid factor for each channel is selected so as to optimise the isotropy of the probe (i.e. equilibrate the peak magnitudes of the three channels) in the liquid. The following equation is used (where output voltages are in units of V*200): E liq 2 (V/m) = U linx * Air Factor x * Liq Factor x + U liny * Air Factor y * Liq Factor y + U linz * Air Factor z * Liq Factor z (3) 4 A chart of the spherical isotropy for probe 0082 is shown in Figure 3. The rotational isotropy is also determined. With the dipole at 90  to the probe axis the rotational isotropy for probe 0082 is +/- 0.25 dB (Figure 4). The final step of the 900 MHz calibration requires the measurement of SAR decay in a generic, spherical phantom and fitting the measured data to one of the two following theoretical predictions of the decay profile: a) SAR decay curve modelled using a 200mm diameter sphere energised by a balanced dipole in a ‘benchmark configuration’ developed as part of an Eureka Project [3]; or, b) SAR decay curve modelled by Flomerics [4] using a sphere and a balanced dipole in a similar test configuration. To measure SAR decay the…

IMMERSIBLE SAR PROBE CALIBRATION REPORT Part Number: IXP – 050 S/N 0082 Calibration factors for 2450 MHz July 2002 Indexsar Limited Oakfield House Cudworth Lane Newdigate Surrey RH5 5DR Tel: +44 (0) 1306 631 233 Fax: +44 (0) 1306 631 834 e-mail: [email protected] 2 INTRODUCTION The calibration Report [1] supplied with this probe (S/N 0082) included the following calibration factors for 900MHz: Probe S/N 0082 at 900 MHzXYZ Air Factors300290330 DCP (V*200)202020 Liquid Factors0.3360.3470.347 At the time of the probe calibration report (March 2002) facilities were not available for probe calibration at 2450MHz. Indexsar have recently established waveguide- based probe calibration apparatus for this frequency and have now performed 2450MHz calibrations on seven probes similar to S/N 0082. The probes are less sensitive at 2450MHz than at 900MHz and the measured calibration factors reflect this. Based on the calibration measurements of seven similar probes in brain liquid (relative permittivity 38.13, conductivity 1.818 S/m), conversion factors that can be applied to the 900MHz calibration for use at 2450MHz have been deduced as below. The average of the factors required to convert a 900MHz calibration into a 2450MHz calibration for brain liquids was 1.53 with a standard deviation of 0.17. Based on these waveguide-based calibration data, the following factors would be appropriate for use with probe S/N 0082 at 2450MHz until the probe receives its next periodic calibration: Probe S/N 0082 at 2450 MHzXYZ Air Factors300290330 DCP (V*200)202020 Liquid Factors0.520.530.53 Prior to use, the validity of these factors should be confirmed by performing a validation measurement using a box phantom and 2450MHz dipole as described in IEEE1528 [1]. For use in body fluids, equivalent conversion factors can be deduced from calibration data for the same seven probes performed in body liquid (relative permittivity 55.28, conductivity 1.92 S/m). The average of the factors required to convert a 900MHz calibration into a 2450MHz calibration for body liquids was 1.71 with a standard deviation of 0.10. Other features of the probe calibration are as detailed in the previous probe calibration Report [1]. In particular, the axial and rotational isotropies listed for 900MHz are appropriate at 2450MHz. 3 WAVEGUIDE PERFORMANCE ASSESSMENT The waveguide apparatus referred to above has been constructed according to the guidelines offered in [2]. In particular, the dimensions and electrical properties of the matching windows have been accurately reproduced and the matching of the waveguides has been checked. Two waveguides with overlapping frequency ranges were compared at a frequency of 2000MHz and the uncertainty in the calibration factors between the two waveguides was 1%. The matching of the waveguides is indicated by return losses of typically –20dB over the frequency bands employed. Separately, the waveguides have been used to repeat calibrations on an Indexsar probe calibrated at the National Physical Laboratory [3]. The same calibration factors have been obtained in the Indexsar waveguides as with those reported by NPL using their own waveguides traceable to national standards. The agreement is within 2% for calibrations at 1800 and 1900MHz at which frequencies the NPL calibrations were performed. UNCERTAINTIES The uncertainties expected of waveguide calibrations are described in IEEE1528 [2]. Liquid properties used in the calibrations were measured at the time of calibration using the Indexsar DiLine dielectric measurement kit, which has uncertainties of around +/- 2% for both permittivity and conductivity for the types of simulant liquids used.
