A Ku Band Broadband Energy Selective Surface Design

In this article, a novel energy selective surface (ESS) working at Ku band is proposed and simulated, providing transient protection for high-power microwave through nonlinear transmission response. By virtue of the double-layer structure and properly selected PIN diode, the ESS proposed achieves binary modes, i.e., transmission and reflection modes. The simulations indicate that the isolation in reflection pattern exceeds 8 dB below 13.7 GHz under the illumination of high-power signal; Similarly, the insertion loss in transmission pattern is less than 1 dB and the 3-dB band ranges from 12 to 15.2 GHz.
