WebFurthermore, the normalized frequency V allows a clear classification of single-mode and multi-mode waveguides. Circular waveguides with a combination of core diameter, core and cladding material that fulfill V < 2.405 for a certain frequency are single-mode DWGs. Normalized frequencies of V ≥ 2.405 indicate Webproposed waveguide is different from the free space wave constant. Needless to mention that for a PCE parallel plate waveguide, the fundamental mode is TEM propagating with 0. This asymmetry is obvious in normalized transverse magnetic field patterns based on equations (7) and (8) as plotted in Fig. 4.
