Electromagnetic energy shield
First Claim
1. A structure for transmitting electromagnetic energy within a first selected frequency range and for preventing the transmission of electromagnetic energy outside said frequency range during a first mode of operation and for substantially preventing the transmission of any electromagnetic energy during the second mode of operation, said structure comprisingan insulative member,a plurality of polygonally-shaped conductive elements positioned in a symmetrical array on at least one surface of said structure,at least a first group of adjacent conductive elements being interconnected by diode elements capable of conduction in a first direction and at least a second group of adjacent conductive elements being interconnected by diode elements capable of conduction along a second direction orthogonal to said first direction, andmeans for placing all of said diode elements substantially simultaneously in their conductive states in said first mode of operation and for placing all of said diode elements substantially simultaneously in their non-conductive states in said second mode of operation.

Abstract
A "shutter" type structure for transmitting electromagnetic energy within a selected frequency range and preventing the transmission of such energy outside such range during a first open shutter mode of operation and for preventing the transmission of any electromagnetic energy during a second closed shutter mode of operation. The structure includes an insulative member having an array of symmetrical conductive elements on at least one surface, such elements being interconnected by diode elements in both vertical and horizontal directions. The diodes are placed in their conductive states during the first mode of operation and in their non-conductive states during the second mode of operation.
