IBM Model 2659-HT2 (Serial #AK-VND0G 02/12) 2. Compaq Model PP2150 (Serial #1V31LDLZ20PG) 3. Toshiba Satellite 1110 System (Part No. PS111T-00CMW, Serial #Y2382109) I. Introduction The U.S. Federal Communications Commission (FCC) has adopted limits of human exposure to RF emissions from mobile and portable devices that are regulated by the FCC [1]. The FCC has also issued Supplement C (Edition 97-01) to OET Bulletin 65 [2] and a more recent version of the same [3] defining both the measurement and the computational procedures that should be followed for evaluating compliance of mobile and portable devices with FCC limits for human exposure to radiofrequency emissions. We have used the measurement procedure for SAR compliance testing of the Wistron NeWeb Model CB-500AG 802.11 a/b/g Cardbus Adapter with three host computers. These host computers shown in Figs. 1-3, respectively, are: 1. IBM Model 2659-HT2. 2. Compaq Model PP2150. 3. Toshiba Satellite 1110 System. The Wistron NeWeb Model CB-500AG 802.11 a/b/g Cardbus Adapter is plugged into each of the above host computers as shown in Figs. 1, 2, and 3, respectively. The peak and average conducted RF power outputs measured at various frequencies for the Wistron NeWeb Model CB-500AG Cardbus Adapter 802.11a Antenna for the normal and turbo modes are given in Table 1. For SAR measurements, two configurations of each of the host PCs relative to the experimental phantom have been used. These are as follows: 2 a. Configuration 1 is for the PC placed on a user's lap. For this configuration, a planar phantom model with inside dimensions 12" x 16.5" (30.5 x 41.9 cm) and a base thickness of 2.0 ± 0.2 mm (recommended in [3]) was used for SAR measurements and the bottom side of each of the laptop computers shown in parts b of Figs. 1, 2, and 3 was pressed against it. Photographs of the three PCs pressed against the bottom of the planar phantom for this "Above-lap" position are given as Figs. 4a, b, and c, respectively. b. Configuration 2: Edge-on position. This configuration corresponds to a bystander close to the outer edge of the cardbus adapter in contact with this edge (separation of 0 cm). For this configuration, the host computer is placed at 90° and the edge of the cardbus adapter is pressed against the bottom of the planar phantom (see Figs. 7, 8, and 9). II. The SAR Measurement System The University of Utah SAR Measurement System has been described in peer-reviewed literature [Ref. 8 -- attached here as Appendix A]. A photograph of the SAR Measurement System is given in Fig. 5. This SAR Measurement System uses a computer-controlled 3-D stepper motor system (Arrick Robotics MD-2A). A triaxial Narda Model 8021 E-field probe is used to determine the internal electric fields. The positioning repeatability of the stepper motor system moving the E-field probe is within ±0.1 mm. Outputs from the three channels of the E- field probe are dc voltages, the sum of which is proportional to the square of the internal electric fields ( ) 2 i E from which the SAR can be obtained from the equation SAR = ( ) 2 i Eσρ, where σ and ρ are the conductivity and mass density of the tissue-simulant materials, respectively [5]. The dc voltages for the three channels of the E-field probe are read by three HP 34401A multimeters and sent to the computer via an HPIB interface.

234IEEE TRANSACTIONS ON ELECTROMAGNETIC COMPATIBILITY, VOL. 41, NO. 3, AUGUST 1999 An Automated SAR Measurement System for Compliance Testing of Personal Wireless Devices Qishan Yu, Om P. Gandhi,Life Fellow, IEEE, Magnus Aronsson,Student Member, IEEE, and Ding Wu Abstract—An automated specific absorption rate (SAR) mea- surement system has been developed for compliance testing of personal wireless devices. Unlike other systems, this system uses a model with a lossy ear-shaped protrusion and the accuracy of this experimental setup has been checked by comparing the peak 1-g SAR’s for ten cellular telephones, five each at 835 and 1900 MHz, with the results obtained using a 15-tissue anatomically based model with the finite-difference time-domain (FDTD) numerical electromagnetic technique. The SAR measurement system uses a three-dimensional (3-D) stepper motor to move a Narda Model 8021 E-field probe to measure the SAR distribution inside a head- shaped tissue-simulant phantom near the radiating device. The head and neck part of the model with an ear-shaped protrusion of 3 mm thickness is made of a lossy outer shell of 5–7 mm thickness of epoxy laced with KCl solution. The phantom is filled with appropriate frequency-specific fluids with measured electrical properties (dielectric constant and conductivity) that are close to the average for gray and white matters of the brain at the center frequencies of interest (835 and 1900 MHz). The implantable E-field probe is calibrated using the FDTD- calculated SAR variations for a slab model at two commonly used frequencies, 835 and 1900 MHz and is checked to have good isotropic characteristics ( 0.23 dB) and a wide dynamic range (0.01–10 W/kg). The system is validated using a 223-mm- diameter sphere model. Peak 1-g SAR’s for ten telephones using different antennas are within 1 dB of those obtained using the FDTD numerical method for the anatomical model of the head and neck region. Index Terms—Experimental phantom with lossy ear, safety compliance testing, validation against computed SAR. I. INTRODUCTION T HE use of cellular telephones and mobile wireless com- munication systems has increased dramatically during the past few years. Meanwhile, there is public concern for safety of RF exposure from these devices. Since the RF exposure is quantified by the mass-normalized rate of electromagnetic energy absorption or the specific absorption rate (SAR), the United States Federal Communications Commission (FCC) requires that the SAR values of new personal wireless devices must meet the prescribed RF safety guidelines [1]. Further- more, since electromagnetic energy absorbed by the human head depends to a large extent on the antenna used for the personal wireless devices [2], knowledge of SAR distributions in the human head can also help the industry to design better antennas to improve the performance of the wireless transceivers. In this regard, we should note that 30–65% of Manuscript received March 10, 1998; revised April 26, 1999.

Publisher Item Identifier S 0018-9375(99)06718-6. the power radiated by the whip antennas used today is wasted by absorption in the human head and hand [2] and this could be reduced greatly. Recent dosimetric studies on the RF exposure to the human body from personal wireless devices have been carried out by both numerical simulation [3]–[5] and experimental measure- ments [6], [7]. Numerical methods using millimeter resolution anatomically based human body models and computer-aided design (CAD) files of cellular telephones can simulate the human body and the cellular phones in detail, respectively, thus providing highly accurate information about the electro- magnetic coupling of the radiating device to the human body [8]. But the numerical technique requires considerable com- putational resources (memory and computation time) for just one test condition of the device. To alleviate this problem, use of the expanding grid finite-difference time-domain (FDTD) method [9] together with the use of the truncated models of the head [10] has resulted in savings of memory requirements by factors in excess of 20, making it possible to compute the high- resolution SAR distributions using workstations instead of parallel computers [8]. Nevertheless, if a device is to be tested for several orientations relative to the head or slightly variable conditions of the relatively unshielded internal circuitry, an easy, fast experimental procedure with validated accuracy and repeatability is of interest. A major requirement of the experimental setup, however, is that the phantom model be designed such that it gives peak 1-g SAR’s that are in good agreement (within 1 dB) with the values obtained using anatomically based models. While none of the previously developed thin shell phantoms can make this claim in this paper, we present an automated SAR measurement system that meets this requirement and can, therefore, be used for compliance testing at both 835 and 1900 MHz. The system is fully automated by a three-dimensional (3-D) stepper motor system controlled by a computer, with a miniature implantable -field probe that is used to determine spatial SAR variations. Using an ear-shaped protrusion of 3 mm thickness, the head and neck part of the phantom model is made of a lossy shell of 5–7 mm thickness of epoxy laced with KCl solution to simulate the thickness of the human skull. This is important since most of the electromagnetic energy absorption for the region of the highest SAR for anatomically based models occurs either for the ear or the internal tissues beyond the skull, which is on the order of 5–7 mm thick. This and the upper part of the torso are filled with a frequency specific fluid with measured electrical properties (dielectric constant and conductivity) close to the average properties of the brain 0018–9375/99$10.001…
