Waveguide Yana murƙushe RF Microwave Millimeter Wave Rediyo

RF waveguide, kalmar yawanci tana rufe nau'o'i daban-daban na raƙuman raƙuman ƙarfe da raƙuman ruwa na saman. Daga cikin su, na farko ana kiransa rufaffiyar waveguide saboda igiyar lantarki da yake watsawa ta kasance gaba ɗaya a cikin bututun ƙarfe. Hakanan ana kiran na ƙarshen buɗaɗɗen waveguide saboda igiyar lantarki da yake jagoranta tana taƙaice ga kewayen tsarin waveguide. Irin waɗannan jagororin mitar rediyo suna taka muhimmiyar rawa a cikin tanda na microwave, radars, tauraron dan adam sadarwa, da kayan haɗin rediyon microwave, inda suke da alhakin haɗa masu watsa injin microwave da masu karɓa zuwa eriyansu. Waveguide kuma ana kiransa haɗin gwargwado torsion. Yana canza alkiblar polarization ta hanyar jujjuya alkiblar faffada da kunkuntar bangarori a bangarorin biyu, ta yadda igiyar lantarki ta ratsa shi, alkiblar polarization tana canzawa, amma alkiblar yadawa ta kasance ba ta canzawa.
A lokacin da ake haɗa igiyoyin igiyar ruwa na millimeter, idan faɗi da kunkuntar ɓangarorin magudanar ruwa biyu sun saba, ya zama dole a shigar da wannan karkatacciyar igiyar ruwa a matsayin canji. Tsawon karkatar da igiyar igiyar ruwa ya kamata ya zama lamba ɗaya na λ g/2, kuma mafi ƙarancin tsayi bai kamata ya zama ƙasa da 2 λ g (inda λ g shine tsayin raƙuman raƙuman raƙuman ruwa).
