摘要:
In this paper, a multilayer optically transparent metamaterial absorber (OTMA) with microwave broadband absorption properties based on indium tin oxide (ITO) and polydimethylsiloxane (PDMS) is designed. The electrical resonance and magnetic resonance generated by the ITO resonance structure of the upper and middle layers make the absorption rate of OTMA exceed 90% at 6.2 GHz-24.6 GHz. The proposed OTMA has polarization insensitivity and wide-angle absorption properties. The experimental results verified that the OTMA has good absorption properties. The absorber has potential application prospects in stealth device windows and electromagnetic shielding structures.
