Amaza amagagasi kagesi angamaza kagesi anobude beza obusuka ku-1 mm ukuya ku-1 m, noma amaza aphakathi kuka-0.3 GHz no-300 GHz. Ububanzi be-microwave buhlanganisa i-ultra-high frequency (UHF) (0.3–3 GHz), ifrikhwensi ephezulu kakhulu (SHF) (3– 30 GHz), kanye namasiginali aphezulu kakhulu (EHF) (30–300 GHz).

IZINHLELO ZOKUXHUMANA:

 

Ngaphambi kokusungulwa kobuchwepheshe bokudlulisa i-fiber optic, izingcingo eziningi zebanga elide zaziphathwa ngezixhumanisi ze-microwave point-to-point ngokusebenzisa amasayithi afana ne-AT&T Long Lines. Kusukela ekuqaleni kwawo-1950, i-frequency division multiplexing yayisetshenziselwa ukuthumela iziteshi zocingo ezingafika ku-5,400 esiteshini ngasinye somsakazo we-microwave, namashaneli omsakazo amaningi afika ayishumi ahlanganiswe abe uthi olulodwa lwe-hop eya endaweni elandelayo, eyayiqhele ngamakhilomitha angama-70. .

 

Amaphrothokholi e-LAN engenantambo, njenge-Bluetooth kanye nokucaciswa kwe-IEEE 802.11, aphinde asebenzise ama-microwave ebhendi ye-ISM engu-2.4 GHz, nakuba i-802.11a isebenzisa ibhendi ye-ISM kanye namafrikhwensi e-U-NII ebangeni elingu-5 GHz. Ilayisense yebanga elide elinelayisense (kufika ku-25 km) Amasevisi Okungena Ku-inthanethi Okungenantambo angatholakala emazweni amaningi ebangeni le-3.5–4.0 GHz (hhayi e-USA nokho).

 

I-Metropolitan Area Networks: Izivumelwano ze-MAN, ezifana ne-WiMAX (I-Worldwide Interoperability for Microwave Access) esekelwe ekucacisweni kwe-IEEE 802.16. Ukucaciswa kwe-IEEE 802.16 kwaklanywa ukuthi kusebenze phakathi kwamafrikhwensi angu-2 kuya ku-11 GHz. Ukusetshenziswa kwezentengiso kuku-2.3GHz, 2.5 GHz, 3.5 GHz kanye no-5.8 GHz.

 

Indawo Ebanzi Yokufinyelela Okungenantambo kwe-Mobile Broadband: Izimiso ze-MBWA ezisekelwe ekucacisweni kwezindinganiso ezifana ne-IEEE 802.20 noma i-ATIS/ANSI HC-SDMA (isb. i-iBurst) yakhelwe ukusebenza phakathi kuka-1.6 no-2.3 GHz ukunikeza ukuhamba kanye nezici zokungena ngaphakathi kwesakhiwo ezifana nomakhalekhukhwini. kodwa ngekhono elikhulu kakhulu le-spectral.

 

Okunye kwe-spectrum ye-microwave ephansi isetshenziswa ku-Cable TV kanye nokufinyelela ku-inthanethi kukhebula elixhumanisayo kanye nomabonakude osakazwayo. Futhi amanye amanethiwekhi omakhalekhukhwini, njenge-GSM, nawo asebenzisa amaza aphansi ama-microwave.

 

Umsakazo we-Microwave usetshenziswa ekusakazeni nasekudluliseleni ngezingcingo ngenxa yokuthi, ngenxa yobude bawo obufushane begagasi, izimpondo eziqondisayo zincane futhi ngenxa yalokho zisebenza kakhulu kunalokho ebezingaba khona kumaza aphansi (amaza amade amaza). Kukhona futhi umkhawulokudonsa omningi ku-spectrum ye-microwave kunakuwo wonke amanye ama-radio spectrum; umkhawulokudonsa osebenzisekayo ongaphansi kuka-300 MHz ungaphansi kuka-300 MHz kuyilapho ama-GHz amaningi engasetshenziswa ngaphezu kuka-300 MHz. Ngokuvamile, ama-microwave asetshenziswa ezindabeni zethelevishini ukuze adlulisele umyalezo usuka endaweni eqhelile uya esiteshini sikamabonakude evenini efakwe izinto ezikhethekile.

 

I-C, X, Ka, noma Ku Bands ye-microwave spectrum isetshenziswa ekusebenzeni kwezinhlelo eziningi zokuxhumana ngesathelayithi. Lawa mafrikhwensi avumela umkhawulokudonsa omkhulu ngenkathi igwema amaza e-UHF aminyene futhi ihlala ngaphansi kokumuncwa komkhathi kwamafrikhwensi e-EHF. I-Satellite TV isebenza kubhendi engu-C yesidlo esikhulu sendabuko Isevisi ye-Fixed Satellite noma i-Ku band ye-Direct Broadcast Satellite. Izinhlelo zokuxhumana zezempi zisebenza kakhulukazi phezu kwezixhumanisi ze-X noma ze-Ku Band, kanti ibhendi ye-Ka isetshenziselwa i-Milstar.

Inzwa Ekude:

 

Ama-radar asebenzisa imisebe yefrikhwensi ye-microwave ukuze athole ububanzi, isivinini, nezinye izici zezinto ezikude. Ama-radar asetshenziswa kakhulu ezinhlelweni ezihlanganisa ukulawula kwethrafikhi yomoya, ukuzulazula kwemikhumbi, nokulawula umkhawulo wejubane lomgwaqo.

 

Ngaphandle kwama-ultrasonic decices, ngezinye izikhathi ama-oscillator e-Gunn diode nama-waveguides asetshenziswa njengezitholi ezinyakazayo zokuvula iminyango okuzenzakalelayo. Iningi lesayensi yezinkanyezi yomsakazo isebenzisa ubuchwepheshe be-microwave.

​

IZINHLELO ZOKUZUZA:

 

I-Global Navigation Satellite Systems (GNSS) ehlanganisa i-American Global Positioning System (GPS), i-Chinese Beidou kanye ne-Russian GLONASS zisakaza amasiginali okuzulazula ngamabhendi ahlukahlukene phakathi kwe-1.2 GHz kanye ne-1.6 GHz.

​

AMANDLA:

 

Ihhavini ye-microwave idlula (i-non-ionizing) imisebe ye-microwave (imvamisa eseduze no-2.45 GHz) ekudleni, ibangele ukushisa kwe-dielectric ngokumunca amandla emanzini, amafutha kanye noshukela oqukethwe ekudleni. Amahhavini e-Microwave abe yinsakavukela kulandela ukuthuthukiswa kwama-cavity magnetrons angabizi.

 

Ukushisa kwe-Microwave kusetshenziswa kabanzi ezinqubweni zezimboni zokomisa nokwelapha imikhiqizo.

 

Amasu amaningi okucubungula ama-semiconductor asebenzisa ama-microwave ukuze akhe i-plasma ngezinjongo ezifana ne-reactive ion etching (RIE) kanye ne-plasma-enhanced chemical vapor deposition (PECVD).

 

Ama-microwave angasetshenziswa ukudlulisa amandla ebangeni elide. I-NASA yasebenza ngeminyaka yawo-1970s nasekuqaleni kwawo-1980 ukuze icwaninge amathuba okusebenzisa amasistimu eSolar Power Satellite (SPS) anemigqa emikhulu yelanga eyayizokwehlisela amandla emhlabeni ngama-microwave.

 

Ezinye izikhali ezilula zisebenzisa amaza amamilimitha ukushisisa ungqimba oluncane lwesikhumba somuntu ukuya ezingeni lokushisa elingabekezeleleki ukuze kwenze umuntu okuqondiwe ahambe. Ukuqhuma kwamasekhondi amabili kwe-95 GHz egxilile ye-focus kushisa isikhumba sibe nezinga lokushisa elingu-130 °F (54 °C) ekujuleni okungu-1/64th we-intshi (0.4 mm). I-United States Air Force kanye nabasemanzini basebenzisa lolu hlobo lwe-Active Denial System.
