摘要：
An exact dispersion relation for the guided modes of a four-layer planar structure with an exponential permittivity profile in the main waveguide layer (slab) is derived for the first time on the basis of the wave approach. Periodicity of the mode characteristics as functions of the cladding thickness is established. The dependence of the energy flux distributions of various modes in the waveguide structure on the thicknesses of the cladding and slab layers is investigated.
