Fitar da hannaye biyu, tare da manyan yatsan yatsa suna nuni zuwa hanyar yaduwar igiyar ruwa, sannan ga wane yatsun hannu na lanƙwasa ke juyawa zuwa wuri ɗaya da polarization.
Idan hannun dama iri ɗaya ne, shi ne polarization na hannun dama; idan hannun hagu iri ɗaya ne, ana yin polarization na hagu.
Na gaba, zan yi amfani da dabaru don bayyana muku. Yanzu a ce akwai raƙuman ruwa masu linzami guda biyu.
Ɗayan shugabanci na polarization shine jagoran x kuma girman shine E1; Hanyar polarization ɗaya ita ce jagorar y kuma girman girman shine E2; duka raƙuman ruwa suna yaduwa tare da hanyar z.
Girman raƙuman ruwa biyu, jimillar filin lantarki shine:
Daga dabarar da ke sama, akwai dama da yawa:
(1) E1≠0, E2=0, sa'an nan polarization shugabanci na jirgin sama ne x-axis.
(2) E1 = 0, E2≠0, to, polarization shugabanci na jirgin sama shine y-axis.
(3) Idan E1 da E2 duka lambobi ne na gaske kuma ba 0 ba, to, jagorar polarization na igiyar jirgin sama ta samar da kusurwa mai zuwa tare da axis x:
