Distance (R) of human body from BSA is varied in the range of . m to . m. Values of whole-body average SAR obtained by hybrid FDTD method closely match with that obtained by SFDTD method. For number of carrier frequency equal to five and R 0:5 m, maximum value of whole-body average SAR obtained by both hybrid FDTD and SFDTD method is found to be . 9 W/kg which decreases either with increase of R or decrease of number of carrier frequencies.

Cell Phones: The EM coupling with Human Body. Witnessing the amazing increase in the use of cell phone handsets, as based on recent market studies, it can be rightly expected that by the end of the first decade of the current century the number of users could rise to four billions. The need emerges, therefore, for investigation of electromagnetic coupling between cell phone antennas and a human with the intention of keeping the anticipated hazard to users at the lowest level.

Salah I. Al-Mously, Marai M. Abousetta. A thorough investigation into the efiect of the hand-hold position on the electro- magnetic (EM) wave interaction of a clamshell-type cellular handset and a human is presented in this paper. This paper is intended to investigate intensely the impact of multipossible hand-hold positions on the electromagnetic (EM) interaction of handset antennas and a human by using a finite-differenc.

This paper presents a thorough investigation into the effect of the external antenna and printed circuit board (PCB) positions in cellular hand-sets on the coupling between the handset and human-head at GSM-900 frequency standard. The antenna performance and the specific absorption rate (SAR) induced in a human head were computed using a Finite Difference Time-Domain based platform (SEMCAD).

Tremendous use of wireless mobile telephony around the globe by people of every age and every walk has spontaneously given rise to the debate about health hazards associated with the use of these devices, thereby emerges a need for research on the EM coupling between cell phone antennas and the human so as the anticipated hazards could be confined to the lowest level. Some scientific studies have linked use of cell phones to headaches, memory loss and cancer, while the industry claims that they are perfectly safe. One well-understood effect of the cell phone radiation is the thermal effect. This book, therefore, investigates the EM coupling between cell phones and human and the factors that may influence this coupling. This book presents a procedure of the computational dosimetry of cell phones, including SAR and the consequence temperature rise evaluations in the head tissues, for different realistic usage patterns and conditions. The contents of this book should be helpful to practicing engineers, graduate students, and professors engaging in evaluating the coupling between cell phones and human, or anyone else who may be interesting in evaluating the cell phone thermal effect.
