Reconfigurable Energy Selective Surface with High Shielding for Large Angles of Incidence Based on Origami

The energy selective surface (ESS) has been widely studied in the field of electromagnetic protection for high power. However, there are still challenges for shielding high-power waves with large angles of incidence. Here, a reconfigurable ESS based on origami is proposed. Utilizing origami, the density of x-direction strips is increased, thus increasing the shielding strength for TM mode. By parameters sweeping, an ESS that satisfies simultaneously shielding requirements for both polarizations can be designed. This work opens an alternative way to design ESS for any angles of incidence and dual polarization.
