Abstract

An IR transparent, but microwave opaque, conductive mesh structure is developed to shield an infrared (IR) system from intense electromagnetic (EM) interference in the microwave range . To prevent potentially damaging EM radiation from penetrating or coupling into the IR system, the IR scanner is enclosed in a Faraday cage. One implication of this IR camera shielding technique is an ability to acquire accurate IR data in any noisy EM environment. A second application of the conductive mesh involves the investigation of EM fields in a copper cylinder, closed at both ends, constructed with a copper mesh section incorporated at one end of the cylinder. Using several positions for the detection material, three-dimensional field profiles are obtained and the results are presented.
