Jd. Wen et al., OPERATION OF NEW-TYPE FIELD DISPLACEMENT ISOLATOR IN RIDGED WAVE-GUIDE, IEEE transactions on microwave theory and techniques, 45(5), 1997, pp. 698-700
A new type ridged-waveguide field-displacement isolator is analyzed in
this paper. Experimental results have been obtained for the isolation
, insert loss, and voltage standing wave ratio (VSWR) in C- and X-band
. The isolation and bandwidth are found to increase obviously.
