Abstract
The leaky modes of dielectric rod waveguides are analysed based on the normalised phase and attenuation constants obtained using Davidenko´s method. It was found that for several lower-order transverse magnetic (TM) modes, the nonphysical leaky mode, antenna mode, reactive mode, and spectral gap all existed below the cutoff frequency of the guided mode.
