Abstract
Using eddy power-flow formulation of electromagnetic fields, a very simple derivation is presented of the relationship between phase index N = c/νp and group index M = c/νg of guided modes in dielectric waveguides, where νp and νg are the phase and group velocities of the mode, and c is the velocity of light in free space.Keywords
