QHAGAMSHELANA NGOKU

Kwiinkqubo zerediyo kunye ne-microwave, i-waveguide yeyona nto iphambili ekusebenzeni kwe-interconnection kunye ne-passive components, ikakhulu kwi-frequency band enikiweyo yokudlulisa ngokufanelekileyo amandla esignali yerediyo, kwaye isakhiwo esiphambili se-waveguide zizinto zesinyithi eziqhuba umbane, ezinokusingatha amanqanaba aphezulu kakhulu ombane.
Njengoko igama lisitsho, amacandelo athe tye e-waveguide aqhagamshelwe ngokuthe ngqo ngaphandle kokutshintsha indlela yawo yokudlulisela isignali, kwaye ubude bunokwenziwa ngokwezifiso ngokwemeko yesicelo, ukusuka kwiisentimitha ezimbalwa ukuya kwiimitha ezimbalwa.
Uyilo kunye nokuveliswa kwamacandelo angqalileyo e-waveguide kufuneka kuqwalaselwe izinto ezahlukeneyo, ezinje ngokusebenza rhoqo, ubungakanani be-waveguide, ukukhethwa kwezinto, iteknoloji yokucubungula, njl. Iindidi eziqhelekileyo zezixhobo zotshintsho lwe-waveguide ziquka utshintsho oluvela kwi-waveguides ezingxande ukuya kwi-waveguides ezijikelezayo, utshintsho phakathi kwe-waveguides ezingxande ezinobukhulu obahlukeneyo, kunye notshintsho oluvela kwi-waveguides ukuya kwimigca ye-coaxial.

Iimbonakalo:

1. Njengomgca wokudlulisela, ii-RF waveguides zisebenza ngokudlulisela amandla ukusuka kwenye indawo ukuya kwenye, zifezekisa ukudluliselwa okusebenzayo ngokunciphisa ilahleko kwinkqubo yokudlulisela amandla. Ulwakhiwo lwesinyithi esingenanto se-waveguides lunokunciphisa kakhulu ilahleko kwinkqubo yokudlulisela amandla.
2. Ngokungafaniyo ne-antenna, amandla awadluliselwa kuyo yonke indawo kwi-waveguide, kodwa abotshelelwe ngaphakathi kwi-waveguide, kwaye kuphela amandla angaphezu kwe-cutoff frequency ethile anokudluliselwa nge-microwave waveguides.

Isicelo:

Ukusetyenziswa kwe-radio frequency waveguides akupheleli nje kwiinkqubo zonxibelelwano kunye ne-radar. Umzekelo, kwi-hyperlens imaging, ii-cascaded arrays ze-straight waveguides kunye ne-curved waveguides zisetyenziselwa ukulinganisa izixhobo ze-refractive index ezilungileyo nezingalunganga ukuze kufezekiswe i-sub-wavelength self-imaging. Le ndlela ibaluleke kakhulu kwi-imaging technology kunye nokuhlanganiswa kwe-photon, ingakumbi ekufezekiseni ulawulo oluchanekileyo lwe-light field kwisikali se-sub-wavelength.

I-QualwaveIzixhobo ze-waveguide straight areas zigubungela uluhlu lwamaza afikelela kwi-91.9GHz, kunye namacandelo e-waveguide straight enziwe ngokwezifiso ngokweemfuno zabathengi. Bamkelekile abathengi ukuba babuze iinkcukacha ezithe vetshe zemveliso.
