Proper and Improper Complex Waves of a Circular Two-Layer Screened Waveguide with an Axial Longitudinally Magnetized Ferrite Layer

Resumo

In a two-layer circular screened waveguide with a longitudinally magnetized inner ferrite layer, the presence of different types of complex waves (CWs) both satisfying and not satisfying the energetic orthogonality condition is shown. The CWs are the solutions of a homogeneous boundary value problem, but, in the first case, the waves are energetically independent and, in the second case, they are associated with the source and indirectly coupled through it.
