Radiation Patterns of Antennas on Plasma Enclosed Cylinders

摘要

The radiation patterns of an infinitesimal longitudinal magnetic line source on a plasma enclosed cylinder are presented. In the cases considered, the plasma is a homogeneous cylindrical layer which is not contiguous with the cylinder. Patterns are shown as a function of the colatitude angle for various values of the layer thickness and the constitutive parameters of the plasma. Transmission through lossy as well as lossless sheaths is considered. The discussion includes a summary of the mathematical problem, computational considerations, and leaky wave effects. (Author)
