| Abstract: | hepending on the polarization rotation effect of the wave transmitted in the structure with aferrite rod magnetized lorgintudinally in a wave guide,two novel typo of wave guide junctions whase tworectangular ends are mutually cross-polarized are designed ,one is gradually varaging and another is cross.when ferrite rods are put into them, ferrite switches controlled bv electric current can be made out. Theswltch at 8mm wave band has following features,loos in the transmitting state no more than 1.0dB,loss inthe cut-off state more than 22dB,the reflecting ratio in the transmitting state no more than 1.3 andresponse time no mlore than 5us. |
