The application of the singularity expansion method (SEM) to the analysis of antennas and electromagnetic scatterers has usually been applied to simple, isolated bodies in free space or to simple bodies near a perfectly conducting ground plane. Theoretical studies of SEM have been applied to these relatively simple geometries to yield significant insight into the radiation and scattering process. In analytically investigating the behavior or antennas in a lossy medium, it is known that in addition to simple pole singularities, there is a branch cut linking two branch points in the complex frequency representation of the antenna response. While significant information regarding the nature of the branch cut and its effect on the antenna response can be obtained by purely analytical methods, a numerical study of this antenna can provide useful results. This paper provides an analysis of the behavior of a linear antenna in a conducting region. Special attention is paid to the importance of the branch cut contribution to the overall antenna response. The possibility of realizing the input admittance or impedance of the antenna via lumped circuit elements is first reviewed for the case of a lossless medium surrounding the antenna, and then extended to the case of an antenna in a lossy medium. |
