Wm. Shi et al., ON THE HIGHER-ORDER MODES IN RECTANGULAR-GROOVE GUIDE, International journal of infrared and millimeter waves, 17(11), 1996, pp. 1957-1967
The propagation characteristics of the higher-order modes in oversize
rectangular-groove guides have been analyzed by using the Method of Li
nes. In the analysis, the cutoff wavenumbers, field distributions and
leaky phenomena are presented and discussed. The leaky mode concept in
troduced in this paper has been found to be useful for analysis. The c
alculated data agreed well with the measured data published.
