Abstract

Personal dosimetry of cellular phone linear and helical antennas for adults and children S. Koulouridis & K.S. Nkita School of Electrical and Computer Engineering, National Technical University of Athens, Greece Abstract The coupling between cellular phone arbitrarily shaped wire antennas and human head models is studied through both a novel semi-analytical technique and Finite-Difference Time-Domain (FDTD) simulations. The semi-analytical technique combines the Green's hctions theory with the Method of Moments (GreedMoM) and is able to model arbitrarily shaped wire antennas radiating in the close proximity of layered lossy dielectric spheres representing simplified models of the human head. The purpose of the development of an accurate semianalytical technique is to provide: (1) a powerful tool for preliminary (worst case) estimation of human head exposure to the field generated by different antenna configurations and (2) a testbed for bencmarking of purely numerical techniques, such as the F
