Tunable Electromagnetic Shutter:

    In this project, the goal was to design a surface capable of adjusting its transmissivity to be either transparent or opaque to incident electromagnetic waves over a broad frequency spectrum. The proposed adjustable surface is a slotted metallic surface with computer controlled switches placed across the slots. By opening and closing the switches the transmissivity of the surface can be adjusted into open and closed states, creating an electronically-controllable EM shutter. More information can be found by contacting me or reading our paper:
