Design of Ultra-wideband and Transparent Absorber based on Resistive Films

摘要

Researching and developing of ultra-wideband capability and high light transmittance have been hot issues in the field of new artificial electromagnetic stealth material. In this paper, a novel transparent metamaterial absorber, made of resistive films and glass, has been presented. The simulation results show that, under the incidence of plane wave, the absorber realizes high absorption during frequency range from 3.5 GHz to 18.5 GHz while keeping insensitive to polarization. A prototype has been fabricated and tested, and the measurement results are in good consistent with simulation. Along with its high transmittance and superior absorption, we expect that the absorber has great potential applications in RCS (Radar Cross Section) reduction and electromagnetic shielding.
