Abstract :
This paper presents the method for evaluation of reflectivity of RF absorber using 3D electromagnetic solver WIPL-D Pro. Absorber design using measurement and trial method is a tedious and time consuming task, and proposed method can be used to make it easier and faster. It has been investigated what is the minimum size of the sample needed for accurate results, how conductivity of the material affects the reflectivity for normal incidence, what is the reflectivity of the absorber for various off normal incident angles for parallel and normal polarization of the wave.
