Ultrabroadband matching of rectangular waveguides with transverse thin layer of dielectric

Matching of tract by the multi-rib diaphragms in multimode band is investigated. Physically and mathematically it is less trivial at broadening of a band of matching four times and more (because of specificity of suppression of a higher modes by inductive loads and placement of strips of diaphragms not only in nodes of E-field). Furthermore, because of small thickness of a plate it is necessary to take into account in field interaction a higher evanescent wave (and also presence in a dielectric of several spatial waves). All this requires a build-up of strict multiwave mathematical models of investigated processes.
