Abstract

An investigation of the effects of fabric over skin, evaluated in terms of transmission coefficient of a five layer model comprising of air-cloth-air-skin-air, is presented in this paper. The analysis is performed in the range of the millimeter waves at 60 GHz. The full wave numerical method Finite Differences Time Domain (FDTD) is used to analyze the investigated fabric-air-skin model. In order to avoid scattering from the edge, a two dimensional model has been considered and Periodic Boundary Conditions (PBC) have been imposed. The effect of varying depth of fabric causes change of transmission coefficient of skin from 10-18%. Results show the value of the transmission coefficient being strictly dependent on the thickness of both the fabric and the air gap between clothes and skin.
