Correlation of infrared measurement results of coupled fields in long cylinders with a dual series solution

A theoretical code for determining electric field distributions in long cylinders is validated by an infrared experimental method. A summary of the theoretical approach using the generalized dual series (GDS) solution is presented. The theoretical solutions for selected geometries used for comparison are depicted as cross-sectional views of experimentally generated infrared (IR) images. The IR images are obtained from microwave interactions and are related to the field intensity at their locations. Qualitative comparisons are made between the field strengths measured using the thermal radiation experimental approach and a theoretical prediction for various frequencies. The experimental and theoretical results show reasonable correlation
