Hluav taws xob cua sov Siv lub tshuab hluav taws xob ntau zaus los ua kom sov cov ntaub ntawv insulating.Cov khoom cua kub tseem ceeb yog lub dielectric.Thaum lub dielectric raug rau ib qho hluav taws xob hloov pauv, nws feem ntau pheej rov polarized (lub dielectric yog nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, thiab qhov tshwm sim ntawm qhov sib npaug tab sis opposite polarity ntawm tus nqi tshwm rau ntawm nws qhov chaw lossis sab hauv), yog li hloov hluav taws xob hluav taws xob hauv hluav taws xob hauv hluav taws xob hauv hluav taws xob.
Cov cua sov nruab nrab siv cov hluav taws xob siab zaus.Nyob rau hauv nruab nrab, luv yoj thiab ultra-luv nthwv dej bands, qhov zaus ntawm ntau pua KHZ mus rau 300 MHZ, hu ua high zaus dielectric cua sov, yog siab tshaj 300 MHZ, kom ncav cuag lub microwave band, hu ua microwave dielectric cua sov.Feem ntau zaus nruab nrab cua sov yog nqa tawm nyob rau hauv lub hluav taws xob teb ntawm ob daim hlau.Microwave dielectric cua sov yog nqa tawm nyob rau hauv lub irradiation ntawm waveguide, resonator los yog microwave kav hlau txais xov hluav taws xob teb.
