Abstract
Some modes of two parallel, circular, lossless, dielectric rods are discussed for identical and nonidentical rods. The electromagnetic boundary-value problem is solved by use of an expansion of the mode field in circular harmonics. Examples of the distribution of flux density are given. The beat wavelength for the beating of energy between the rods computed for identical rods is compared with approximate results of coupled-mode theory.
