A Necessary and Sufficient Condition for Having Independent TE and TM Modes in an Anisotropic Waveguide
Wei Jiang, Jie Liu, Qin Li +4
Whether there exist independent transverse electric (TE) and transverse magnetic (TM) modes in a metallic waveguide filled with an anisotropic medium is a fundamental question in e…
