Design and Development of Banana Leaves-based Double-layer Microwave Absorber

Abstract

A Double-layer banana leaves-based absorber is designed and can be treated as a potential alternative to conventional MAM. The dielectric relaxation parameters of the dry banana leaves in powder form and the composites of dry banana leaves and charcoal powder have are measured by OCP method using vector network analyzer in the frequency range of 1–16 GHz. Further, the return loss of two single-layers and a double-layer with a thickness of 4 and 8.02 mm, respectively, is investigated in the frequency range of 1–20 GHz. Results show that the electromagnetic properties along with absorption performance of the double layer absorber are appreciably ameliorated as compared to its single-layer counterparts.
