Gg. Denisov et Da. Lukovnikov, OHMIC QUALITY OF RESONATORS SHAPED BY CORRUGATED GUIDE SECTIONS AT FREQUENCIES NEAR BRAGG STOP BANDS, International journal of infrared and millimeter waves, 18(3), 1997, pp. 595-603
The effect of ohmic loss decrease in corrugated waveguide is studied f
or the case of period, equal to half of longitudinal wave length (so c
alled pi-type oscillations). As demonstrated, in periodical guide ther
e are pi-type waves with ohmic quality growing approximatelly as a cub
e of guide radius, which looks very attractive for different applicati
ons.
