Reconfigurable fluidic shutter for selectively shielding an antenna array

摘要

It includes that first surface and second surface are spaced apart, and limit a cavity that restructural flow control door, which selectively covers aerial array,; The pump is configured to that attenuation electromagnetic radiation of pump liquid, and the metal or alloy that such as liquefies is constituted, and flows in and out cavity. The not reflection electromagnetic wave on the first and second surfaces, such as microwave or other RF radiation.
