ABSTRACT:
A reconfigurable fluidic shutter for selectively shielding an antenna array includes a first surface and second surface spaced apart and defining a cavity; and a pump configured to pump liquid that attenuates electromagnetic radiation, such as a liquefied metal or alloy composition, into and out of the cavity. The first and second surface are transparent to electromagnetic radiation, for instance, microwave or other RF radiation.
