ULTRA-WIDEBAND WAVES THROUGH MULTILAYER PLANAR,CYLINDRICAL AND SPHERICAL MODELS

This work focuses on modeling part of human body as multilayer planar, cylindrical and spherical shape. Simulations on various human body models using the ultra-wide band are carried out at different incident angles in two scenarios: through wall and without the wall. The absorbed power densities of the layers of a multilayer object are found by taking the material properties and geometric parameters into account. The simulated results are demonstrated and thus compared with the theoretical formulations for the verification. Consequently, the effects of frequency change and wall placement in front of the object are discussed. Our findings indicate that the incident angle of waves effect the reflected and absorbed signal amplitude in the body and with the existence of the wall, the signal amplitude level decrease in the range of 0.1% and 0.01% depending on the layer of the body it absorbs.
