- Low VSWR
Hauv xov tooj cua zaus thiab microwave tshuab, lub waveguide yog qhov ua tau zoo tshaj plaws ntawm kev sib tshuam thiab cov khoom siv passive, feem ntau yog nyob rau hauv qhov muab zaus band kom zoo xa xov tooj cua zaus teeb liab lub zog, thiab lub ntsiab qauv ntawm lub waveguide yog hlau conductive cov ntaub ntawv, muaj peev xwm ua tau zoo heev. qib zog.
Raws li lub npe qhia, lub waveguide ncaj seem txuas ncaj qha yam tsis hloov nws cov teeb liab kev taw qhia, thiab qhov ntev tuaj yeem hloov kho raws li daim ntawv thov scenario, xws li los ntawm ob peb centimeters mus rau ob peb meters.
Kev tsim thiab kev tsim ntawm waveguide ncaj seem yuav tsum tau xav txog ntau yam, xws li kev khiav hauj lwm zaus, waveguide loj, xaiv cov khoom siv, kev siv tshuab, thiab lwm yam. Cov hom waveguide hloov cov cuab yeej muaj xws li kev hloov ntawm lub voj voog waveguides mus rau lub voj voog waveguides, kev hloov ntawm cov duab plaub ntawm waveguide. ntau qhov sib txawv, thiab kev hloov ntawm waveguides mus rau coaxial kab.
1. Raws li cov kab sib kis, cov kab sib txuas ncaj nraim ua haujlwm los ntawm kev xa hluav taws xob los ntawm ib qho chaw mus rau lwm qhov, ua tiav kev sib kis tau zoo los ntawm kev txo qhov poob hauv cov txheej txheem xa hluav taws xob. Lub hollow hlau qauv ntawm lub waveguide tuaj yeem txo qhov poob hauv cov txheej txheem kev sib kis ntawm lub zog.
2. Nyob rau hauv sib piv rau lub kav hlau txais xov, lub zog tsis yog radiated mus rau tag nrho qhov chaw nyob rau hauv lub waveguide, tab sis yog khi nyob rau hauv lub waveguide, thiab tsuas yog lub zog saum toj no ib tug tshwj xeeb cutoff zaus yuav kis tau los ntawm lub waveguide ncaj seem.
Daim ntawv thov ntawm waveguide ncaj seem tsis txwv rau kev sib txuas lus thiab radar systems. Piv txwv li, nyob rau hauv cov duab hyperlens, cascaded arrays ntawm ncaj waveguides thiab nkhaus waveguides yog siv los simulate zoo thiab tsis zoo refractive index cov ntaub ntawv kom ua tiav sub-wavelength nws tus kheej duab. Cov txheej txheem no yog qhov tseem ceeb hauv kev yees duab thev naus laus zis thiab kev sib koom ua ke ntawm photon, tshwj xeeb tshaj yog nyob rau hauv kev ua tiav ntawm kev tswj xyuas meej ntawm lub teeb teb ntawm sub-wavelength scale.
Qualwavecov khoom siv waveguide ncaj seem npog cov zaus ntau txog 91.9GHz, nrog rau kev hloov kho waveguide ncaj sSsections raws li cov neeg siv khoom xav tau. Zoo siab txais tos cov neeg siv khoom los nug cov khoom lag luam ntxiv.
