Hauv cov xov tooj cua zaus thiab microwave systems, lub waveguide yog qhov ua tau zoo tshaj plaws ntawm kev sib txuas thiab cov khoom passive, feem ntau hauv cov zaus band muab los xa cov teeb liab zaus xov tooj cua zoo, thiab cov qauv tseem ceeb ntawm lub waveguide yog cov khoom siv hlau conductive, tuaj yeem tswj cov qib fais fab siab heev.
Raws li lub npe qhia, cov ntu ncaj qha ntawm waveguide tau txuas ncaj qha yam tsis hloov nws cov kev taw qhia ntawm kev xa xov, thiab qhov ntev tuaj yeem hloov kho raws li qhov xwm txheej ntawm daim ntawv thov, xws li ob peb centimeters mus rau ob peb meters.
Kev tsim thiab tsim cov ntu ncaj nraim ntawm waveguide yuav tsum xav txog ntau yam, xws li zaus ua haujlwm, qhov loj ntawm waveguide, kev xaiv cov khoom siv, kev siv tshuab ua haujlwm, thiab lwm yam. Cov hom khoom siv hloov waveguide feem ntau suav nrog kev hloov pauv ntawm cov waveguides plaub fab mus rau cov waveguides puag ncig, kev hloov pauv ntawm cov waveguides plaub fab ntawm ntau qhov ntau thiab tsawg, thiab kev hloov pauv ntawm waveguides mus rau cov kab coaxial.

Nta:

1. Ua ib txoj kab xa hluav taws xob, cov RF waveguides ua haujlwm los ntawm kev hloov lub zog los ntawm ib qho chaw mus rau lwm qhov, ua tiav kev xa hluav taws xob zoo los ntawm kev txo qhov poob hauv cov txheej txheem xa hluav taws xob. Cov qauv hlau hollow ntawm waveguide tuaj yeem txo qhov poob hauv cov txheej txheem xa hluav taws xob.
2. Tsis zoo li lub kav hlau txais xov, lub zog tsis tau tawm mus rau hauv tag nrho qhov chaw hauv lub waveguide, tab sis raug khi rau hauv lub waveguide, thiab tsuas yog lub zog saum toj no qhov zaus txiav tshwj xeeb tuaj yeem xa mus los ntawm cov microwave waveguides.

Daim Ntawv Thov:

Cov kev siv ntawm cov xov tooj cua zaus waveguides tsis txwv rau kev sib txuas lus thiab radar systems. Piv txwv li, hauv hyperlens imaging, cascaded arrays ntawm cov waveguides ncaj thiab cov waveguides nkhaus yog siv los ua qauv cov khoom siv refractive index zoo thiab tsis zoo kom ua tiav sub-wavelength tus kheej-imaging. Cov txheej txheem no yog qhov tseem ceeb heev hauv kev siv tshuab imaging thiab photon kev koom ua ke, tshwj xeeb tshaj yog hauv kev paub txog kev tswj hwm qhov tseeb ntawm lub teeb teb ntawm sub-wavelength scale.

Qualwavecov khoom siv waveguide ncaj nraim npog qhov zaus txog li 91.9GHz, nrog rau cov waveguide ncaj nraim raws li cov neeg siv khoom xav tau. Txais tos cov neeg siv khoom kom nug ntxiv cov ntsiab lus ntawm cov khoom.
