Resonance Behavior of an Obliquely-Oriented Conducting Wire Object Above a Halfspace

This paper examines the effect of a halfspace on the residues of the extracted resonant modes of an obliquely-oriented conductive wire target above it.

Summary:This paper examines the effect of a halfspace on the residues of the extracted resonant modes of an obliquely-oriented conductive wire target above it. Previous studies have focused on the case where the target is in free space, but in this case, the halfspace interacts electromagnetically with the target and alters the residue. The results show that the residue of the fundamental mode is affected by the dielectric properties of the halfspace, while the residues of higher-order modes remain similar as the properties change. These findings provide insights for designing automated recognition solutions for targets above halfspaces.
