In this paper, we proposed a type of all-dielectric metamaterial (ADM) with continues dielectric ceramics. The ceramics, possess high permitivity and low loss, are designed in fishnet shape. With this shape, continuous displacement currents are inspired inside high permitivity ceramics for the incident electromagnetic wave. Then, Lorentz type of electric and magnetic resonances are emerged simultaneously,...
In this paper, a monolayer high-impedance surface broadband absorber with honeycomb lattices based on the flexible metamaterial are designed. The simulated results are shown that the relative absorption bandwidth is from 13 to 19.1 GHz, also it can be observed that the simulated absorption exceeds 95% almost from 13.1 to 19 GHz and the absorber is polarization insensitive for the incident wave under...
This paper put forward a windmill-shaped left-handed metastructure, which consists of four central-symmetric spiral lines and four metallic sticks. An equivalent circuit of the left-handed unit is modeled based on transmission line theory. Then a multi-band antenna is designed by applying this windmill-shaped unit, just with central-symmetric spiral and cross-bar slits loaded on a rectangular patch...
