Calculating the Characteristic Impedance of Finlines by Transverse Resonance Method
IEEE transactions on microwave theory and techniques
The characteristic impedance of finlines with up to three slots is calculated by a rigorous hybrid-mode analysis which includes the finite metallization thickness and finite depth of the mounting grooves. The transverse resonance principle utifiied reduces considerably the order of the involved matrix eigenvalue problem. The propagation constants for the fundamental HE~mode (and EHO mode at related structures), as well as for the higher order modes (up to HE,), and the characteristic impedancesdoi:10.1109/tmtt.1986.1133284 fatcat:qbeaj2jhejdtvmxaxye7jjlkay
