Boundary problem solution for eigenmodes in coaxial quad-ridged waveguides
The boundary problem for eigenmodes in coaxial quad-ridged waveguides has been solved by the transverse field-matching technique. The formulas obtained provide possibilities to calculate cutoff wave numbers and electric and magnetic fields modes.
