Quantification of Thermographic Mapping Techniques

Thermographic mapping of microwave fields is a method of imaging the electromagnetic field in a region of space by viewing the heating it produces when interacting with a material. As the microwave field interacts with a material, some of the electromagnetic energy may be converted into heat. This heat can be viewed in several ways; the most useful technique developed to date involves an infrared camera. The objective of this work is to develop appropriate theoretical and experimental practices to allow for the design and manufacture of an electromagnetic absorbing screen. The absorbing screen must exhibit a significant heat rise for a small amount of incident electromagnetic energy while not disturbing the electromagnetic field it is measuring. Thus, the design of the absorber involves a trade-off between these two desirable properties.... Thermographic mapping, Infrared (IR) camera, Electromagnetic energy.
