Flexible Reconfigurable Metamaterial Absorber injecting EGaIn

초록

In this paper, we propose a flexible and wideband metamaterial absorber. The proposed absorber consists of Jerusalem cross (JC) resonators with slotted circular rings, chip resistors, and microfluidic channels. The proposed absorber can switch the absorption frequency band by injecting a liquid metal eutectic gallium indium alloy (EGaIn) into the channels. The performance of the absorber was demonstrated through full-wave simulation and through measurements employing prototypes.
