Abstract. An infinite system of
infinite coupled integrated dielectric waveguides is considered. Integrated
waveguides containing dielectric slab between two metal screens as a central
region and two outer regions formed by two-dimensional arrays of via holes in
the slab are investigated. Dominant eigen modes of the waveguide system are
studied with help of a numerical solution of electromagnetic problem obtained
with help of a finite elements method. Frequency dependencies of eigen modes
retardation factors and coupling coefficients are obtained. Structures with
arrays with rectangular and hexagonal grids are considered. An approximate
model of the investigated structure on the base of averaged dielectric constant
of periodic media is proposed.
Keywords: coupled waveguides,
