A reconfigurable dual-band metasurface for EMI shielding of specific electromagnetic wave components

Metasurfaces are becoming more of an interest to the research community because of the unusual electromagnetic properties that can be achieved. This paper presents a reconfigurable metasurface for EMI shielding purposes. In particular, a dual-band Jersualem cross is developed and pin diodes are use to interconnect elements to control the specific polarization properties of the shield. It is shown that the response of the shield to specific field components can be controlled with simple control voltages. Simulations are validated with measurements throughout this work.
