Parametric Study of Microwave Absorption in Lossy Dielectric Slabs

Abstract

This paper presents a thorough study of the behaviour of microwave absorption occurring in lossy dielectric slabs as used for microwave absorbers. The influence of the various parameters governing absorption is demonstrated : dielectric constant, conductivity, thickness of slab and frequency. It is shown that for several combinations of values for these parameters absorption can be maximized to up to unity, i.e. all the incident power is absorbed.
