Qhov sib txawv tseem ceeb ntawm cov kab sib txuas thiab elliptical polarization yog tias nyob rau hauv kab polarization, hluav taws xob hluav taws xob ntawm lub teeb raug txwv rau ib lub dav hlau uas qhov kev nthuav tawm tshwm sim, thiab nyob rau hauv voj voog polarization, muaj ob lub dav hlau linear hauv hluav taws xob. thaj chaw ntawm lub teeb uas yog perpendicular rau ib leeg whereas, nyob rau hauv elliptical polarization, hluav taws xob teb ntawm lub teeb yog nyob rau hauv ib tug elliptical propagation.
Hauv lub dav hlau-polarized lub teeb, tag nrho cov nthwv dej muaj kev taw qhia ntawm kev co. Muaj peb hom loj ntawm lub teeb polarization: linear polarization, ncig polarization, thiab elliptical polarization.
Dab tsi yog Linear Polarization?
Linear polarization yog hom teeb pom kev zoo polarization qhov chaw hluav taws xob ntawm lub teeb raug txwv rau ib lub dav hlau thaum lub teeb pom kev tshwm sim. Nyob rau hauv lwm yam lus, nws yog ib tug confinement ntawm vector ntawm ib tug hluav taws xob teb los yog lub vector ntawm magnetic teb rau ib tug muab dav hlau raws li cov kev taw qhia ntawm lub propagation ntawm lub teeb. Peb tuaj yeem hais tias lub dav hlau nthwv dej yog linearly polarized thaum tsis muaj qhov sib txawv ntawm x thiab y cov khoom siv hluav taws xob ntawm lub teeb.
Vim polarization yog dab tsi?
Lub voj voog polarization yog hom lub teeb polarization thaum muaj ob lub dav hlau kab uas nyob ib sab ntawm ib leeg tshwm sim los ntawm hluav taws xob ntawm lub teeb. Hauv lwm lo lus, nws yog txoj hauv kev ntawm polarization ntawm EMR nthwv dej uas yog vector ntawm hluav taws xob teb lossis vector ntawm magnetic teb zoo li ua rau lub voj voog perpendicular mus rau txoj kev ntawm lub teeb propagation nyob rau hauv uas qhov zaus yog sib npaug zos rau ntawm. lub yoj.
Qhov tseem ceeb tshaj, ob lub dav hlau no muaj qhov sib npaug ntawm qhov sib npaug txawm tias lawv cov lus qhia nyob rau ib leeg. Tab sis cov theem ntawm cov dav hlau txawv ntawm ib leeg. Hauv cov ntsiab lus no, peb tuaj yeem pom tias kev nthuav tawm ntawm lub teeb tshwm sim nyob rau hauv ib ncig. Feem ntau, hom polarization no tseem ceeb hauv kev sib txuas lus satellite.
YElliptical Polarization yog dab tsi?
Elliptical polarization yog ib hom ntawm lub teeb polarization qhov chaw hluav taws xob ntawm lub teeb nyob ntawm qhov kev nthuav tawm elliptical uas qhov amplitude thiab theem sib txawv ntawm ob lub dav hlau linear tsis sib npaug. Hauv lwm lo lus, nws yog txoj kev polarization ntawm EMR nthwv dej nyob rau hauv ib txoj kev uas lub ntsis ntawm lub vector ntawm hluav taws xob teb qhia ib tug ellipse, thiab cov kev taw qhia yog zoo li cov kev taw qhia ntawm propagation.
Qhov txawv ntawm Kab Kab thiab Elliptical Polarization yog dab tsi?
Qhov sib txawv tseem ceeb ntawm linear ncig thiab elliptical polarization yog tias nyob rau hauv linear polarization, hluav taws xob hluav taws xob ntawm lub teeb raug txwv rau ib lub dav hlau uas qhov kev nthuav tawm tshwm sim thiab nyob rau hauv voj voog polarization, muaj ob lub dav hlau linear hauv hluav taws xob. ntawm lub teeb uas yog perpendicular rau ib leeg whereas, nyob rau hauv elliptical polarization, hluav taws xob teb ntawm lub teeb yog nyob rau hauv ib tug elliptical propagation. Linear polarization yog ib txoj hauv kev yooj yim polarization thaum lub voj voog polarization yog ntau dua li linear polarization. Elliptical polarization yog ib txoj hauv kev nyuaj heev.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm kab voj voog thiab elliptical polarization.
Summary – Linear vs Circular vs Elliptical Polarization
Qhov sib txawv tseem ceeb ntawm cov kab sib txuas thiab elliptical polarization yog tias nyob rau hauv kab polarization, hluav taws xob hluav taws xob ntawm lub teeb raug txwv rau ib lub dav hlau uas qhov kev nthuav tawm tshwm sim, thiab nyob rau hauv voj voog polarization, muaj ob lub dav hlau linear hauv hluav taws xob. thaj chaw ntawm lub teeb uas yog perpendicular rau ib leeg whereas, nyob rau hauv elliptical polarization, hluav taws xob teb ntawm lub teeb yog nyob rau hauv ib tug elliptical propagation.
