Frequency band - esisetyenziswa ngokubanzi kwi izixhobo kunye nezixhobo mihla

Superhigh uluhlu frequency - na radiation magnetic, leyo kuluhlu phakathi ophezulu-frequency ezitsho TV kude lefoni. Xa amazwe IsiNgesi abathetha ibizwa ngokuba uluhlu microwave kuba ngamaza lincinane kakhulu xa kuthelekiswa kunye nencum kunomathotholo. Ezi oscillations ke oluphakathi phakathi radiation ukukhanya kunye spectrum radio eqhelekileyo, Noko ke, kufuneka ngaxeshanye iimpawu yokukhanya kunye nerediyo amaza. Njengoko ngokunjalo radiation thermal, zisasazwe ngokohlobo umqadi ube mnye, kubonakala. Ngokuqhelekileyo Amaza kunye nokwanda kumgca othe ngqo, kunye ukungqubana zonke izinto eziqinileyo. Ngoko ke, abaninzi yerada eriyali - kukwandisa izinto woqondo ngohlobo yezibuko ezinkulu okanye lenses.

Kufuneka kuqatshelwe ukuba uluhlu frequency iyafana kwimitha usasazo onke, kwaye ngokufanelekileyo, ziya kwenziwa ngeendlela ezifanayo. radiation microwave iqulathe theory lakudala kwamaza erediyo, ukuze isetyenziswe ngempumelelo njengendlela yonxibelelwano. Kodwa ke, kubaluleke kakhulu ukuba ine rhoqo ephezulu ukuze ke afumane amathuba amaninzi ukugqithiswa kweenkcukacha - kuyanceda ukuphucula ukusebenza unxibelelwano. Le Ukufana amadlozi ukukhanya kunceda ukuba luncedo radar kunye nezinye izicelo zobuchwepheshe.

Le yefrikhwensi kananjalo kusetyenziswa unxibelelwano satellite ukudlulisa okanye iinkcukacha ngaphezu imigama emide. Ngokusebenzisa izixhobo ezikhethekileyo ngekhompyutha ziyanyuswa kwaye retransmitted microwave ukuba sisasazwa kwizikhululo emhlabeni. Isiseko wokuqala ukuvela kwi 60s lwekhulu yokugqibela, xa ngoncedo kwabo yasasazwa losasazo TV.

Ngokusekelwe kumava elidlulileyo, uqhagamshelo Hewana ethile imveliso enjalo zaphuhliswa. Okwangoku, ezifana omsindo uluhlu frequency inceda izigidi zabantu ukuba ukubukela amawaka lamajelo kumgangatho ekumgangatho ophezulu. Kwakhona usetyenziswe okudlulisela ifowuni, umabonwakude, imiqondiso ifeksi kunye data digital.

Kweli hlabathi lanamhlanje zobungakanani ultra-high uluhlu - unyango ubushushu iimveliso zokutya ekhaya kunye nezityalo ukutya. I-eneji eyenziwe izibane enamandla ezizodwa, kanzulu Mna kuloo mqulu encinane, yaye ngaloo ndlela kukho unyango ubushushu ukutya. Ngenxa ezi iimayikhroweyivi imitha kunye oveni microwave asebenza cwaka, ukuba compact kwaye zicocekile. izixhobo ezinjalo ziye zasetyenziswa ngempumelelo ekhitshini kwi moya, kwi w / d iimoto, zokutyela kunye noomatshini umbane ezitalatweni, apho kufuneka ukuba balungiselele ngokukhawuleza ezinye izidlo.

Kufuneka kuqatshelwe ukuba indima enkulu ekufundeni iimpawu ngekhompyutha eziqinileyo ezahlukeneyo udlalwa radiation microwave. Uluhlu lwe mhlaba otsalayo inceda elektroni ezamahala ukujikeleza moya lowo nkqo ulwalathiso lo mhlaba otsalayo. Ukongeza, ukuba umzimba eqinileyo ukwalathisa imitha le microwave, ngoko ako ngamandla. Lo mkhwa - a livakale cyclotron, kwaye zingasetyenziswa ukuba ukulinganisa olusebenzayo ubunzima electron. Ngokwemilinganiso ezinjalo, oosonzululwazi baye bafumana oluninzi ulwazi olubalulekileyo malunga semiconductors kunye neempawu ze-elektroniki, kwakunye isinyithi kunye metalloid.
