The spectrum of electromagnetic waves guided by a plasma layer

摘要: The modal spectrum of a lossless, homogeneous and isotropic planar plasma layer is shown to contain contributions from surface waves complex modes in addition the usual continuous characteristic open structures. These discrete are only E-mode type occur whenever dielectric constant e p negative. may be forward or backward they carry power opposite directions air regions. appear always degenerate pairs as consequence no real but account for large reactive fields neighborhood sources. For E with positive values , all H modes, purely continuous; however, nonspectral leaky ways then present which significant radiation considerations.
