Abstract

The authors propose and describe a novel analysis technique using an advanced wire grid model to obtain the scattered field of a lossy dielectric object. This model has concentrated impedances, which are equivalent to the surface impedance, loaded into each wire junction, and thus it is called a loaded wire grid model. The calculation time using this model is almost the same as that using the ordinary wire-grid method. A human body is treated here as an example of a lossy dielectric object. The manner of choosing the appropriate parameters of this model is clarified by comparing the calculated and the experimental results. The calculated results using suitable model parameters are in good agreement with experimental results. It is also shown that this technique can be used to calculate the power absorbed by the lossy dielectric object.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
