Abstract

An infrared (IR) detection technique is applied to the problem of measuring electric fields both interior and exterior to metallic cylinders under microwave illumination. An IR measurement technique which can be used to detect microwave fields, both continuous wave (CW) and pulsed, is described in this paper. The technique involves placing a thin lossy detection screen material in the region over which the electromagnetic (EM) field is to be mapped. The fields are detected through Joule heating that occurs then EM energy is absorbed by the screen material. The induced temperature distribution, detected by an IR scanning system via emitted thermal radiation, at the surface of the screen corresponds to the EM field intensities in the screen. Thus, the two dimensional field distribution can be seen in nearly real time and is now extended to the interior and exterior problem. The simultaneous observation from a dual band Thermovision System is also being investigated.
