Jagorar igiyar igiyar ruwa (ko jagorar raƙuman ruwa) layin watsa tubular maras tushe ne da aka yi da madugu mai kyau. Kayan aiki ne don yada makamashin lantarki (mafi yawan watsa igiyoyin ruwa na lantarki tare da tsayin daka akan tsari na santimita) Kayan aikin gama gari (mafi yawan watsa igiyoyin lantarki tare da tsayin raƙuman ruwa akan tsari na santimita).
Zaɓin girman jagorar raƙuman raƙuman raƙuman ruwa ya kamata a yi la'akari da waɗannan abubuwan:
1. Waveguide bandwidth matsala
Don tabbatar da cewa igiyoyin lantarki na lantarki a cikin kewayon mitar da aka ba su na iya yaduwa a cikin yanayin TE10 guda ɗaya a cikin waveguide, ya kamata a yanke sauran hanyoyin oda, sannan b
2. Waveguide ikon iya aiki matsala
Lokacin yada ƙarfin da ake buƙata, jagorar wave ba zai iya rushewa ba. Haɓakawa da kyau b na iya ƙara ƙarfin wutar lantarki, don haka b ya kamata ya zama babba gwargwadon yiwuwa.
3. Attenuation na waveguide
Bayan microwave ya wuce ta hanyar waveguide, ana fatan cewa ikon ba zai yi asarar da yawa ba. Ƙara b na iya yin ƙarami, don haka b ya kamata ya zama babba kamar yadda zai yiwu.
Idan aka yi la’akari da abubuwa masu jan hankali, girman jagororin raƙuman ruwa na rectangular gabaɗaya an zaɓi su kamar:
a=0.7λ, λ shine tsayin daka-tsalle na TE10
b= (0.4-0.5) a
Yawancin raƙuman raƙuman ruwa na rectangular an tsara su tare da yanayin a: b = 2: 1, wanda aka sani da daidaitattun raƙuman ruwa, ta yadda za a iya samun iyakar iyakar bandwidth na 2: 1, wato, rabon mitar mafi girma zuwa mafi ƙarancin yankewa. mitar shine 2:1. Don inganta ƙarfin wutar lantarki, ana kiran waveguide tare da b>a / 2 babban waveguide; domin rage girma da nauyi, da waveguide tare da b
Matsakaicin adadin bandwidth wanda jagorar waveguide na madauwari zai iya yadawa shine 1.3601: 1, wato, rabon mafi girman mitar yanayi guda ɗaya zuwa mafi ƙarancin yanke yanke shine 1.3601: 1. Shawarar mitar aiki don jagorar raƙuman raƙuman raƙuman ruwa shine mitar 30% sama da mitar yankewa da 5% ƙasa da mitar yanke yanayin mafi girma na biyu. Waɗannan dabi'un da aka ba da shawarar suna hana tarwatsa mitoci a ƙananan mitoci da aiki multimode a mafi girma mitoci.
