Muma frequency eredhiyo uye ma microwave systems, waveguide ndiyo inoshanda zvakanyanya yekubatanidza uye zvikamu zvisingashande, kunyanya mubhendi rema frequency rakapihwa kuti ritumire zvinobudirira simba rechiratidzo chema frequency eredhiyo, uye chimiro chikuru che waveguide zvinhu zvinofambisa simbi, zvinogona kubata masimba akawandisa.
Sezvinoratidzwa nezita racho, zvikamu zvakananga zvewaveguide zvakabatana zvakananga pasina kuchinja gwara rayo rekutumira masaini, uye kureba kwacho kunogona kugadziriswa zvichienderana nemamiriro ekushandiswa, kubva pamasendimita mashoma kusvika pamamita mashoma.
Kugadzirwa nekugadzirwa kwezvikamu zve waveguide zvakananga kunofanirwa kufunga nezvezvinhu zvakasiyana-siyana, zvakaita sekushanda kwenguva yakareba, saizi ye waveguide, kusarudzwa kwezvinhu, tekinoroji yekugadzirisa, nezvimwewo. Mhando dzakajairika dzezvishandiso zve waveguide zvinosanganisira kuchinja kubva kuma waveguides e rectangular kuenda kuma waveguides akatenderera, kuchinja pakati pe rectangular waveguides ehukuru hwakasiyana, uye kuchinja kubva kuma waveguides kuenda kuma coaxial lines.

Zvimiro:

1. Senzira yekutumira, maRF waveguides anoshanda nekutamisa simba kubva kune imwe nzvimbo kuenda kune imwe, zvichiita kuti kutamiswa kubudirire nekuderedza kurasikirwa mukuita kwekutumira simba. Chimiro chesimbi isina chinhu chewaveguides chinogona kuderedza zvakanyanya kurasikirwa mukuita kwekutumira simba.
2. Kusiyana neantenna, simba harisviswi munzvimbo yese iri muwaveguide, asi rinosungirirwa mukati mewaveguide, uye simba riri pamusoro penguva yakatarwa chete ndiro rinogona kutumirwa kuburikidza nema microwave waveguides.

Kushandiswa:

Mashandisirwo ema "radio frequency waveguides" haasi ekungotaura chete uye ma "radar systems". Semuenzaniso, mu "hyperlens imaging", "cascaded arrays" ema "straight waveguides" uye "curved waveguides" anoshandiswa kutevedzera zvinhu zvakanaka nezvakaipa zve "refractive index" kuti zvikwanise kuzvifungidzira zviri mu "sub-wavelength". Iyi nzira yakakosha zvikuru muhunyanzvi hwemifananidzo uye kubatanidzwa kwe "photon", kunyanya mukuita kuti chiedza chidzoke zvakanaka pa "sub-wavelength scale".

QualwaveZvikamu zvemagetsi zvinofamba newaveguide zvinofukidza huwandu hwemafrequency hunosvika 91.9GHz, pamwe nezvikamu zvemagetsi zvinofamba newaveguide zvinoenderana nezvinodiwa nevatengi. Tinokugamuchirai vatengi kuti mubvunze rumwe ruzivo nezvechigadzirwa.
