Abstract:

This article presents a detailed electromagnetic analysis of planar multi-layered dielectric structures for low-power industrial applications. Adopting the analogy between the multi-section transmission line transformers and planar multi layered dielectrics, the material properties of each layer are determined. Design of a novel planar multi-layered absorber, namely the parabolic absorber, has been proposed in the article. The transformer is designed using commercially available low-loss dielectric materials for a frequency of 10 GHz. The feasibility of the absorber is analyzed for both normal and oblique incidences. © 2011 Taylor & Francis Group, LLC.
