Loop-to-Loop Close-Range EM Signal Transfer Through a Conducting Thin Sheet – An Analytical Study Based on the Cagniard-DeHoop Technique

A dedicated version of the Cagniard-DeHoop technique is applied to analyze the close-range electromagnetic (EM) field signal transfer between two small loop antennas through a highly-contrasting, thin conducting sheet. It is demonstrated that the solution methodology leads to useful asymptotic closed-form expressions describing the signal transfer in terms of Kirchhoff-circuit elements. Illustrative numerical examples that validate the results are presented.
