Ultra-broadband microwave metamaterial absorber
TLDR
In this article, a microwave ultra-broadband polarization-independent metamaterial absorber is demonstrated, which is composed of a periodic array of metal-dielectric multilayered quadrangular frustum pyramids.Abstract:
A microwave ultra-broadband polarization-independent metamaterial absorber is demonstrated. It is composed of a periodic array of metal-dielectric multilayered quadrangular frustum pyramids. These pyramids possess resonant absorption modes at multi-frequencies, of which the overlapping leads to the total absorption of the incident wave over an ultra-wide spectral band. The experimental absorption at normal incidence is above 90% in the frequency range of 7.8–14.7 GHz, and the absorption is kept large when the incident angle is smaller than 60°. The experimental results agree well with the numerical simulation.read more
