This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

Abstract: In recent years, active multifunctional metamaterials (AMFMMs) have been extensively investigated due to their excellent adaptivity to the variation in electromagnetic (EM) environments.

Abstract: In this article, a 3-D frequency-selective surface (FSS) with high selectivity and large angular stability of 70° is proposed. The equivalent circuit model of the single-layer FSS is first ...
