Cov yam ntxwv ntawm photonic siv lead ua kis sib txawv
Xaiv cov qauv ntoo sib txawv tuaj yeem tsim cov kab sib txawv txwv tsis pub muaj kab thiab dav dav; kev sib txawv ntawm qhov tsis sib xws thiab qhov sib piv sib txawv yog sib luag rau cov txwv tsis pub muaj dav nyob hauv qee qhov; raws li qhov sib piv ntawm qhov sib piv, cov kem sib txawv tau kawm, thiab elliptical sab pom cov qauv ntawm lub cev tsis txawv ntau ntawm cov qauv ntawm lub tog raj kheej, tab sis nws cov hom TE thiab TM muaj ntau cov kev txwv txiav tsis pub piv nrog cov qauv cylindrical. Cov qauv ntawm cov txwv uas tsis pub hloov tau hloov ntau, thiab cov kev ua tiag tiag ua rau photonic muaju. Vim tias qhov tseeb tsis txaus, cov qauv cylindrical feem ntau raug rhuav tshem thiab dhau los ua lub ntsej muag lossis lwm yam duab, yog li cov qauv cylindrical ntawm cov photonic siv lead ua yog qhov tseem ceeb hauv kev txheeb xyuas ntawm photonic band qhov sib txawv.
