In this letter, a multifunctional reconfigurable metamaterial (MRMM), featuring three operating states is introduced based on the multi-scale integration of hierarchical microchannel configuration and liquid metal (LM) regulation strategy. The MRMM can flexibly switch among full-band transmission from 8 GHz to 15 GHz with an insertion loss (IL) of 1 dB, second-order bandpass from 11.64 GHz to 13.7...Show More
In this study, a highly visible transparent broadband metamaterial radar absorber based on micron-scale meshed metal is presented. The designed absorber is a sandwich structure composed of lossy layer, transparent dielectric layer and reflective layer from top to bottom. Taking advantage of the high visible transmittance and good conductivity of micron-scale metal, different meshed metal patterns ...Show More
In this paper, a multilayered multifunctional switchable frequency selective surface based on liquid metal (LM) is proposed. The structure comprises three microfluidic layers. The switching among three operating states, including full-band transmission, highly-selective bandpass, and full-band reflective is achieved by exploiting the mobility of LMs. It is demonstrated that the proposed design is ...Show More
