XHUMANA MANJE

Ezinhlelweni zemvamisa yomsakazo kanye ne-microwave, i-waveguide iwukusebenza okuphezulu kakhulu kokuxhumana kanye nezingxenye ezingasebenzi, ikakhulukazi kubhendi yemvamisa enikeziwe ukuze idlulise ngempumelelo amandla esignali yemvamisa yomsakazo, futhi isakhiwo esiyinhloko se-waveguide yizinto eziqhuba insimbi, ezingaphatha amazinga aphezulu kakhulu wamandla.
Njengoba igama lisikisela, izingxenye eziqondile ze-waveguide zixhunywe ngqo ngaphandle kokushintsha indlela yokudlulisela isignali, futhi ubude bungenziwa ngokwezifiso ngokwesimo sohlelo lokusebenza, kusukela kumasentimitha ambalwa kuya kumamitha ambalwa.
Ukuklama nokukhiqizwa kwezingxenye eziqondile ze-waveguide kudinga ukucabangela izici ezahlukahlukene, njengobuningi bokusebenza, usayizi we-waveguide, ukukhethwa kwezinto, ubuchwepheshe bokucubungula, njll. Izinhlobo ezivamile zamadivayisi okuguqula i-waveguide zifaka phakathi ukuguquka kusuka kuma-waveguides angunxande kuya kuma-waveguides ayindilinga, ukuguquka phakathi kwama-waveguides angunxande anobukhulu obuhlukene, kanye nokuguquka kusuka kuma-waveguides kuya emigqeni ye-coaxial.

Izici:

1. Njengomugqa wokudlulisela, ama-RF waveguide asebenza ngokudlulisa amandla ukusuka endaweni eyodwa kuya kwenye, efinyelela ukudluliselwa okuphumelelayo ngokunciphisa ukulahleka enqubweni yokudlulisela amandla. Isakhiwo sensimbi esingenalutho se-waveguide singanciphisa kakhulu ukulahleka enqubweni yokudlulisela amandla.
2. Ngokungafani ne-antenna, amandla awakhishwa kuyo yonke indawo ku-waveguide, kodwa aboshelwe ngaphakathi ku-waveguide, futhi amandla angaphezu kwemvamisa ethile yokusika kuphela angadluliselwa ngama-waveguide e-microwave.

Isicelo:

Ukusetshenziswa kwama-waveguides e-radio frequency akukhawulelwe kwezokuxhumana kanye nezinhlelo ze-radar. Isibonelo, ekufomeni kwe-hyperlens, ama-cascaded arrays ama-waveguides aqondile kanye nama-waveguides agobile asetshenziselwa ukulingisa izinto ze-refractive index ezinhle nezimbi ukuze kufezwe ukuzibona ngokwakho kwe-sub-wavelength. Le ndlela ibaluleke kakhulu kubuchwepheshe bokufometha kanye nokuhlanganiswa kwe-photon, ikakhulukazi ekuqalisweni kokulawulwa okunembile kwensimu yokukhanya esikalini se-sub-wavelength.

I-QualwaveIzingxenye eziqondile ze-waveguide zimboza ububanzi bemvamisa efika ku-91.9GHz, kanye nezingxenye eziqondile ze-waveguide ezenziwe ngokwezifiso ngokwezidingo zamakhasimende. Siyakwamukela amakhasimende ukuthi abuze ngemininingwane yomkhiqizo eyengeziwe.
