Infrared Detection of Microwave Induced Surface Currents on Flat Plates

摘要

The surface currents induced by electromagnetic radiation incident on conductive bodies produce joule heating measurable by infrared techniques. Qualitative studies have shown that surface current amplitude information can be determined from the surface heating pattern. A quantitative analysis, via infrared techniques, of surface current amplitude distributions on the flat plates is presented, and the results are compared to actual current distributions determined from electromagnetic computer code calculations and probe measurements. This correlation study on flat plates is an essential step toward the infrared measurement of current amplitude distributions on more complex shapes.
