Abstract

This paper presents the design and experimental evaluation of a novel asymmetric metasurface absorber(MA) for wideband, polarization-insensitive operation in the X-band. The unit cell integrates an arrow-shaped resonator on an FR-4 substrate backed by a copper plate. By incorporating three strategically placed resistors, the design achieves over 80% absorption at 8-12 GHz. This absorber is suitable for applications in stealth applications and EMI shielding.
