Rigorous Representations of Source-ezcited Electromagnetic Fields in Cylindrically Stratified Gyrotropic Media

摘要：

We consider electromagnetic fields excited by spatially bounded, arbitrary given sources in the presence of a gyrotropic cylinder surrounded by a homogeneous gyrotropic background medium. The axis of symmetry of the considered cylindrical structure is assumed to coincide with the gyrotropic axis. The total field is sought in terms of the vector modal solutions of source-free Maxwell s equations. By demanding completeness of the modal spectrum and using a continuity argument,we determine the content of the modal spectrum and obtain an eigenfunction expansion of the source-excited field in terms of discrete-and continuous-spectrum modes. We discuss representations of source-excited fields for particular cases of interest.
