Electromagnetic coupling to thin-wire structures in complex cavities

Electromagnetic coupling through a narrow-slot aperture to a region containing a thin-wire structure is computed as a characterization of electromagnetic compatibility and interference (EMC/EMI) issues. Results are presented for coupling through a narrow slot to a single, thin, straight segment of wire in a cavity. The slot has width and depth and the wire has arbitrary position and orientation within the coupled region. By varying the wire/slot geometries the interaction of the respective resonance structures is examined. Results for a coupled half-space as well as results for a complex cavity enclosure are presented.
