Zusammenfassung: | We solve the problem of electrodynamic analysis of the mode content in a circular waveguide with radial metal T-ridges and layered dielectric filling. Algorithms for calculation of cutoff wave numbers, components of the electromagnetic fields of the H and E waves, and the propagation constants of the hybrid HE and EH waves are developed with allowance for the features of the field behavior near a metal ring-shaped sector of finite thickness. The dependences of normalized cutoff wave numbers and propagation constants on the geometric sizes of the structure and its dielectric permittivity are studied. The electromagnetic field of the fundamental and higher modes of the H and E waves and hybrid modes is visualized. |
