Te
How should the concepts of transverse modes, longitudinal modes, fundamental mode, TEM, TE, and TM in lasers be understood?
Electromagnetic waves in waveguides are classified into TE, TM, and TEM modes. TE modes have magnetic components, TM modes have electric components, and TEM modes have neither in the propagation direction. These modes determine the field distribution in transmission lines or cavities. Waveguides can support single-mode or multi-mode transmission depending on their dimensions and cutoff frequencies.
