XHUMANA MANJE

Kumasistimu omsakazo nama-microwave, i-waveguide iwukusebenza okuphezulu kakhulu kokuxhumanisa kanye nezingxenye ze-passive, ikakhulukazi ebhendini yefrikhwensi enikeziwe ukuze idlulise ngempumelelo amandla esignali yefrikhwensi yomsakazo, futhi ukwakheka okuyinhloko kwe-waveguide izinto eziqhutshwayo zensimbi, ezingaphatha amazinga wamandla aphezulu kakhulu.
Njengoba igama liphakamisa, izingxenye eziqondile ze-waveguide zixhunywe ngokuqondile ngaphandle kokushintsha isiqondiso sokudlulisa isignali, futhi ubude bungenziwa ngokwezifiso ngokusho kwesimo sohlelo lokusebenza, kusukela kumasentimitha ambalwa kuya kumamitha ambalwa.
Idizayini kanye nokukhiqizwa kwezigaba eziqondile ze-waveguide kumele zicabangele izici ezihlukahlukene, ezifana nemvamisa yokusebenza, usayizi we-waveguide, ukukhethwa kwezinto, ubuchwepheshe bokucubungula, njll. Izinhlobo ezivamile zamadivayisi okuguqula i-waveguide zifaka ukuguqulwa ukusuka kumagagasi angama-rectangular ukuya kumagagasi ayindilinga, ukuguqulwa phakathi kwamagagasi angunxande osayizi abahlukene, kanye noshintsho olusuka kumagagasi kuya emigqeni ye-coaxial.

Izici:

1. Njengolayini wokudlulisela, i-RF waveguides isebenza ngokudlulisela amandla isuka endaweni eyodwa iye kwenye, ithola ukudluliswa okuphumelelayo ngokunciphisa ukulahleka kwenqubo yokudlulisa amandla. Isakhiwo sensimbi esingenalutho se-waveguide singanciphisa kakhulu ukulahlekelwa kwinqubo yokudlulisa amandla.
2. Ngokungafani nothi, amandla awakhisheli kuso sonke isikhala ku-waveguide, kodwa aboshelwe ngaphakathi kwe-waveguide, futhi amandla angaphezu kwe-cutoff frequency ethile kuphela angadluliswa ngamagagasi e-microwave.

Isicelo:

Izinhlelo zokusebenza zamagagasi egagasi omsakazo azikhawulelwanga kwezokuxhumana namasistimu e-radar. Isibonelo, emfanekisweni wama-hyperlens, ama-waveguide aqondile namagagasi agobile asetshenziselwa ukulingisa izinto zenkomba ebukeka kahle nezingezinhle ukuze kuzuzwe ukuzicabangela kwe-wavelength engaphansi. Le nqubo ibaluleke kakhulu kubuchwepheshe be-imaging kanye nokuhlanganiswa kwe-photon, ikakhulukazi ekufezeni ukulawulwa okunembile kwenkambu yokukhanya esikalini se-wavelength engaphansi.

Qualwaveihlinzeka ngezigaba eziqondile ze-waveguide zimboza imvamisa yobubanzi obufika ku-91.9GHz, kanye nezigaba eziqondile ze-waveguide eziqondile ngokwezidingo zamakhasimende. Siyakwamukela amakhasimende ukuze ubuze eminye imininingwane yomkhiqizo.
