Ib qho kev taw qhia kho qhov muag yog lub cev qauv uas coj cov nthwv dej electromagnetic hauv qhov muag pom. Cov hom kev kho qhov muag muaj xws li optical fiber ntau thiab pob tshab dielectric waveguides ua los ntawm yas thiab iav.

txhais tau li cas los ntawm kev kho qhov muag waveguide?

Ib qho kev taw qhia kho qhov muag yog tus qauv spatial inhomogeneous rau kev taw qhia lub teeb, piv txwv li rau txwv thaj chaw spatial uas lub teeb tuaj yeem nthuav tawm. Feem ntau, lub waveguide muaj thaj tsam ntawm qhov nce qhov ntsuas qhov taw qhia, piv nrog qhov nruab nrab ib puag ncig (hu ua cladding).

Puas yog fiber ntau optical waveguide?

Optical fiber ntau yog tiag tiag a waveguide rau lub teebthiab ua haujlwm raws li lub hauv paus ntsiab lus hu ua tag nrho kev xav sab hauv.… Tag nrho cov kev xav sab hauv tshwm sim thaum lub yoj yoj yoj tawm tsam thaj tsam ntawm ob yam khoom sib txawv, yog tias lub kaum sab xis ntawm qhov xwm txheej loj dua lub kaum sab xis tseem ceeb.

waveguide siv rau dab tsi?

Ib waveguide yog ib qho khoom siv hluav taws xob kab noj khoom siv hauv microwave kev sib txuas lus, tshaj tawm, thiab kev teeb tsa radar Ib lub waveguide muaj cov duab plaub lossis cylindrical hlau raj lossis yeeb nkab. Electromagnetic teb propagates lengthwise. Waveguides feem ntau siv nrog horn kav hlau txais xov s thiab phaj kav hlau txais xov s.

Dab tsi yog ob hom optical waveguides los ntawm hom qauv?

Muaj ob lub ntsiab ntawm cov qauv kho qhov muag waveguide: cov kauj ruam ntsuas thiab qib ntsuas.
