Incident angle insensitive double negative (DNG) metamaterial absorber

Youngsoo Jang、Joungyoung Lee、Sungjoon Lim2011-12-01Asia-Pacific Microwave Conference

An incident angle insensitive double negative metamaterial absorber by using hexagonal shape is described. It can absorb any incident angle transverse electromagnetic (TEM) wave because of its hexagonal symmetry shape. In spite of its structure, the absorber achieved a 81.5% absorptivity at 10.52 GHz in numerical resu…
