Lits'ebetsong tsa maqhubu a seea-le-moea le microwave, waveguide ke ts'ebetso e phahameng ka ho fetesisa ea khokahano le likarolo tse sa sebetseng, haholo-holo sehlopheng se fanoeng sa frequency ho fetisa matla a leqhubu la radio ka nepo, 'me sebopeho sa mantlha sa waveguide ke lisebelisoa tse tsamaisang tšepe, tse ka sebetsanang le maemo a phahameng haholo a matla.
Joalokaha lebitso le bontša, likarolo tse otlolohileng tsa waveguide li hokahane ka kotloloho ntle le ho fetola tataiso ea phetisetso ea matšoao, 'me bolelele bo ka etsoa ho latela maemo a ts'ebeliso, ho tloha ho lisenthimithara tse' maloa ho isa ho limithara tse 'maloa.
Moralo le tlhahiso ea likarolo tse otlolohileng tsa waveguide li hloka ho nahana ka lintlha tse fapaneng, joalo ka maqhubu a ts'ebetso, boholo ba waveguide, khetho ea thepa, theknoloji ea ts'ebetso, joalo-joalo Mefuta e tloaelehileng ea lisebelisoa tsa phetoho ea waveguide e kenyelletsa ho fetoha ho tloha ho li-waveguide tse nang le mahlakore a mabeli ho ea ho li-waveguides tse chitja, ho fetoha pakeng tsa maqhubu a mahlakore a mabeli a boholo bo fapaneng, le ho fetoha ho tloha ho maqhubu a maqhubu ho ea ho mela ea coaxial.

1. Joaloka mohala oa phetisetso, li-waveguides tsa RF li sebetsa ka ho fetisetsa matla ho tloha sebakeng se seng ho ea ho se seng, ho finyella phetiso e sebetsang ka ho fokotsa tahlehelo ea mokhoa oa ho fetisetsa matla. Sebopeho sa tšepe se se nang letho sa waveguide se ka fokotsa tahlehelo haholo ts'ebetsong ea phetisetso ea matla.
2. Ho fapana le antenna, matla ha a fetisetsoe sebakeng sohle ka har'a waveguide, empa a tlameletsoe ka hare ho waveguide, 'me matla feela a ka holim'a sekhahla se itseng sa cutoff a ka fetisoa ka li-waveguides tsa microwave.

Kopo:

Lisebelisoa tsa maqhubu a maqhubu a seea-le-moea-pono ha li felle feela lits'ebetsong tsa likhokahano le radar. Mohlala, litšoantšong tsa li-hyperlens, li-waveguide tse otlolohileng le li-waveguide tse kobehileng li sebelisoa ho etsisa lisebelisoa tse ntle le tse mpe tsa index ho fihlela boinahano ba sub-wavelength. Mokhoa ona o bohlokoa haholo ho theknoloji ea litšoantšo le ho kopanngoa ha photon, haholo-holo ho phethahatsa taolo e nepahetseng ea sebaka sa leseli ho sub-wavelength scale.

Qualwavee fana ka likarolo tse otlolohileng tsa waveguide tse koahelang lebelo la maqhubu ho fihla ho 91.9GHz, hammoho le likarolo tse otlolohileng tsa waveguide ho latela litlhoko tsa bareki. Amohela bareki ho botsa lintlha tse ling tsa sehlahisoa.
