A Novel Method of Energy Selective Surface for Adaptive HPM/EMP Protection

In this letter, a new method of energy selective surface (ESS) is presented for adaptive high-power microwave/electromagnetic pulse (HPM/EMP) protection, and a self-actuated ESS is designed with super-dense diode arrays. A prototype of size 35 × 35 cm
²
is fabricated to evaluate the performance of ESS, and an experiment under HPM radiation is carried out at 1.3 GHz. Results of measurements show that ESS has an energy low-pass characteristic of adaptive protection.
