Abstract:
The eigenwaves diffraction problem in a plane waveguide by strips is considered. Strips
are placed in the same plane. Waveguide is filled by non-ideal dielectric. The operator
approach in combination with the spectral-domain approach is used. Paired integral
equations for single strip are solved by the spectral-domain approach. The structure's
properties in the whole with finite number of discontinuities are obtained by the
operator approach by use the reflection and transmission operators of single strip.
Dependencies of reflection and transmission coefficients as a function of strip length
and distance between strips are represented. They allow to determine passbands and
stopbands. The properties of such structures allow to create frequency selection devices
with high level of parameters.
