Mu machitidwe a wailesi ndi mawayilesi a microwave, waveguide ndiye magwiridwe antchito apamwamba kwambiri olumikizirana ndi magawo osagwira ntchito, makamaka mu gulu lomwe lapatsidwa pafupipafupi kuti azitha kufalitsa mphamvu zamagetsi zamagetsi, ndipo mawonekedwe akulu a waveguide ndi zida zopangira zitsulo, zimatha kupirira kwambiri. milingo mphamvu.
Monga momwe dzinalo likusonyezera, zigawo zowongoka za waveguide zimalumikizidwa mwachindunji popanda kusintha njira yotumizira ma siginecha, ndipo kutalika kwake kumatha kusinthidwa malinga ndi momwe ntchito ikugwiritsidwira ntchito, kuyambira ma centimita angapo mpaka mamita angapo.
Kupanga ndi kupanga zigawo zowongoka za waveguide ziyenera kuganizira zinthu zosiyanasiyana, monga kuchuluka kwa magwiridwe antchito, kukula kwa ma waveguide, kusankha kwazinthu, ukadaulo wopanga, ndi zina zambiri. kukula kosiyanasiyana, ndikusintha kuchokera ku ma waveguide kupita ku mizere ya coaxial.

Mawonekedwe:

1. Monga chingwe chotumizira, zigawo zowongoka za waveguide zimagwira ntchito mwa kusamutsa mphamvu kuchokera kumalo ena kupita kumalo ena, kukwaniritsa kupatsirana bwino mwa kuchepetsa kutayika kwa njira yotumizira mphamvu. Mapangidwe achitsulo opanda kanthu a waveguide amatha kuchepetsa kwambiri kutayika kwa njira yotumizira mphamvu.
2. Mosiyana ndi mlongoti, mphamvuyo siimalowetsedwa mu danga lonse la waveguide, koma imamangiriridwa mkati mwa waveguide, ndipo mphamvu yokhayo yomwe ili pamwamba pa mafupipafupi a cutoff imatha kufalitsidwa kudzera mu zigawo zowongoka za waveguide.

Ntchito:

Kugwiritsa ntchito zigawo zowongoka za waveguide sikungokhala pazolumikizana ndi makina a radar. Mwachitsanzo, pakuyerekeza kwa ma hyperlens, mindandanda yowongoka ya ma waveguide owongoka ndi mafunde opindika amagwiritsidwa ntchito kuyerekezera zinthu zabwino ndi zoyipa za refractive index kuti akwaniritse kudziyerekeza kwapang'onopang'ono. Njira imeneyi ndi yofunika kwambiri mu luso lojambula zithunzi ndi kuphatikizika kwa photon, makamaka pakukwaniritsidwa kwa kayendetsedwe kabwino ka malo ounikira pa sub-wavelength scale.

Qualwaveamapereka zigawo zowongoka za waveguide zimaphimba ma frequency mpaka 91.9GHz, komanso magawo osinthika a waveguide molunjika malinga ndi zomwe makasitomala amafuna. Takulandilani makasitomala kuti mufunse zambiri zamalonda.
