Abstract
A design of ultra-broadband absorber for ultra-large angles is proposed in this paper. The absorber is composed of bi-layered butterfly-shaped metasurfaces loaded with lumped resistors, adhesives and metal ground. The simulation results show that the proposed absorber reveals 90% absorptivity from 4.46-16.00GHz within the range of 60°-75°. Especially, the Absorber can maintain 90% absorptivity from 5.53-13.87GHz at the incident angle of 80°.
