Coupling frequencies of rectangular waveguide-dielectric resonators partially filled with dielectric

The partial-region method is employed to solve the problem of quasinatural mode H_n0(p+) of coupled waveguide-dielectric resonators with axially and centrally symmetric placement of inserts in an overmoded waveguide. Good agreement is obtained between the calculated and experimental results. The dynamics of coupling-frequency behavior is studied.Khar'kov State University.
