Cov ntsiab lus ntawm polarized teeb
Cov asymmetry nruab nrab ntawm cov kev taw qhia ntawm kev vibration thiab cov kev taw qhia ntawm kev tshaj tawm yog hu ua polarization, thiab nws yog qhov pom tseeb tshaj plaws tias lub shear yoj sib txawv los ntawm lwm cov kev ntev. Tsuas yog cov shear yoj muaj polarization. Lub teeb yoj hluav taws xob yog electromagnetic tsis, yog li cov kev taw qhia ntawm lub teeb yoj tshaj tawm yog qhov kev taw qhia ntawm electromagnetic yoj tawm. Cov hluav taws xob kev co vector E thiab cov hlau nplaum sib nqus vector H hauv lub teeb nthwv dej yog ob qho tib si sib txuam rau qhov kev tshaj tawm v, yog li lub teeb nthwv dej yog qhov hloov hluav taws xob thiab nws muaj polarization. Polarized lub teeb yog hu ua polarized teeb.
