Slime Based Meta-Structure Absorber for X-band Applications

Abstract

Herein, an X-band meta-structure absorber is proposed with a thickness of $3\text{mm}(=\lambda/10)$. The absorber is designed and developed using viscous slime embedded in cuboidal structures made of flexible silicone rubber substrate. The absorber is backed by aluminium tape. The developed absorber shows a reflection loss of - 36.92 dB (>90% absorption) at 9.46 GHz with a -10 dB bandwidth of 2 GHz. In addition, the absorber shows cross-polarization insensitivity.
