Abstract :
The combined method of moment (MoM) and generalized multipole techniques (GMT) is used to determine the electromagnetic scattered field from a body embedded in multilayered medium. Appropriate approaches are adopted for the inverse scattering problem to obtain the form of the object. The multilayered medium parameters can be lossy and dispersive of interest for simulating a human body. To make such an analysis tractable for the short-pulse applications of interest here, we have employed the method of complex images to evaluate the Sommerfeld integrals characteristic of the dyadic layered-medium Green´s function. Some examples to obtain the results of the form of the body are presented, wherein fundamental wave phenomology is elucidated. Finally future developments of the proposed techniques are indicated.
