Hagaha waveguide (ama hagaha mawjadaha) waa khad gudbin tuubo ah oo godan oo ka samaysan kirishboor wanaagsan. Waa aalad lagu faafiyo tamarta korantada (badanaa ku gudbinta hirarka korantada ee leh mowjado dhererkoodu yahay isku xigxiga sentimitir) Aaladaha caadiga ah (inta badan gudbinta hirarka korantada ee mawjadaha isku xiga ee sentimitir).
Doorashada cabbirka waveguide-ka leydigu waa inay tixgelisaa arrimaha soo socda:
1. Waveguide dhibaatada bandwidth
Si loo hubiyo in mowjadaha elektromagnetic-ka ee ku dhexyaala inta jeer ee la bixiyay ay ku faafi karaan hal qaab TE10 ee waveguide, hababka kale ee dalabka sare waa in la gooyaa, ka dibna b
2. Waveguide dhibaatada awoodda awoodda
Marka la faafinayo awoodda loo baahan yahay, waveguide ma burburin karo. Si habboon u korodhka b waxay kordhin kartaa awoodda korantada, markaa b waa inay noqotaa mid weyn intii suurtagal ah.
3. Attenuation of waveguide
Ka dib marka microwave-ku uu dhex maro waveguide, waxaa la rajeynayaa in korontadu aysan aad u lumin doonin. Kordhinta b waxay ka dhigi kartaa hoos u dhigista mid yar, markaa b waa inay noqotaa mid weyn intii suurtagal ah.
Iyadoo la tixgelinayo arrimaha soo jiidashada leh, cabbirka mawjadaha leyliga ah ayaa guud ahaan loo doortay sida:
a=0.7λ, λ waa mawjada dhererka la jaray ee TE10
b=(0.4-0.5)a
Inta badan mawjadaha leyliga ah waxaa loo qaabeeyey iyada oo leh saamiga a: b=2:1, oo loo yaqaan waveguides-ka caadiga ah, si saamiga ugu badan ee xajmigu yahay 2:1 la gaaro, taas oo ah, saamiga inta jeer ee ugu sarreeya ilaa kan ugu hooseeya inta jeer waa 2:1. Si loo hagaajiyo awoodda awoodda, waveguide leh b>a / 2 waxaa loo yaqaan waveguide sare; si loo yareeyo mugga iyo miisaanka, waveguide leh b
Saamiga ugu badan ee xajmiyeed ee mawjadaha wareegtadu ay faafin karto waa 1.3601: 1, taas oo ah, saamiga inta jeer ee hal-habka ugu sarreeya ilaa inta jeer ee ugu hooseeya ee goynta waa 1.3601: 1. Inta jeer ee lagu taliyey in uu shaqeeyo mawjadaha leydigu waa inta jeer ee 30% ka sarreeya inta jeer ee la jarayo iyo 5% oo ka hooseeya habka labaad ee ugu sarreeya inta jeer ee goynta. Qiimayaashan lagu taliyay ayaa ka hortagaya faafinta soo noqnoqda ee soo noqnoqoshada hoose iyo hawlgalka multimode ee soo noqnoqda sare.
