Abstract
A switchable Frequency Selective Surface (FSS) in which the switchable elements are Plasma-shells. Plasma-shells as described herein allow for control or ‘reconfiguration’ of the FSS electromagnetic (EM) properties.
Claims4
A device composed of at least one or more gas encapsulating structures comprising a plasma-shell sandwiched between two or more patterned conductive sheets with said gas encapsulating structure electrically connected to the sheets such that a voltage potential across the two sheets will form a continuous volume of plasma within each gas encapsulating structure.
A device composed of at least one or more gas encapsulating structures mounted to one or more patterned conductive sheets with said gas encapsulating structure electrically connected to the sheets such that incident energy induces a sufficient E-field within the gas encapsulating structures to ionize at least a portion of the gas to plasma.
