Wareegtada Waveguide
Dulmar
Mabda'a shaqada ee wareegtada waveguide waxay ku salaysan tahay gudbinta asymmetric ee goobta magnetic.Marka ay calaamaddu ka soo gasho khadka gudbinta waveguide hal jiho, agabka magnetic ayaa hagi doona calaamadda si ay ugu gudbiso jihada kale.Sababtoo ah xaqiiqda ah in qalabka birlabku uu kaliya u dhaqmo calaamadaha jihada gaar ah, waveguide Circulator s waxay gaari kartaa gudbinta calaamadaha aan jiho lahayn.Dhanka kale, iyada oo ay ugu wacan tahay sifooyinka gaarka ah ee qaab dhismeedka waveguide iyo saameynta qalabka magnetic, Wareegga waveguide wuxuu gaari karaa go'doon sare wuxuuna ka hortagayaa muujinta calaamadaha iyo faragelinta.
Wareegtada waveguide waxay leedahay faa'iidooyin badan.Marka hore, waxay leedahay luminta gelinta hoose waxayna yareyn kartaa hoos u dhaca calaamadaha iyo luminta tamarta.Marka labaad, wareegtada waveguide waxay leedahay go'doon sare, taas oo si wax ku ool ah u kala saari karta calaamadaha wax gelinta iyo soo saarista kana fogaanayo faragelinta.Intaa waxaa dheer, wareegtada waveguide waxa ay leedahay sifooyin ballaadhan oo ay taageerto tiro balaadhan oo ah soo noqnoqoshada iyo shuruudaha bandwidth.Intaa waxaa dheer, waveguide Circulator s waxay u adkeysanayaan awood sare waxayna ku haboon yihiin codsiyada awooda sare leh.
Waveguide Circulators waxaa si weyn loogu isticmaalaa nidaamyada RF iyo microwave ee kala duwan.Nidaamyada isgaarsiinta, waveguide Circulator s waxaa loo isticmaalaa in lagu go'doomiyo calaamadaha u dhexeeya gudbinta iyo helitaanka qalabka, ka hortagga dhawaaqyada iyo faragelinta.Nidaamyada raadaarka iyo anteenada, waveguide Circulator s ayaa loo isticmaalaa si looga hortago muujinta calaamadaha iyo faragelinta, iyo horumarinta waxqabadka nidaamka.Intaa waxaa dheer, waveguide Circulator s waxa kale oo loo isticmaali karaa tijaabinta iyo cabbiraadda codsiyada, falanqaynta calaamadaha iyo cilmi-baarista shaybaarka.
Marka la dooranayo oo la isticmaalayo waveguide Circulator s, waxaa lagama maarmaan ah in la tixgeliyo qaar ka mid ah xuduudaha muhiimka ah.Tan waxaa ku jira kala duwanaanshaha soo noqnoqda ee hawlgalka, kaas oo u baahan xulashada kala duwanaansho joogto ah oo ku habboon;Darajada go'doominta, hubinta saameynta go'doominta wanaagsan;Luminta gelinta, isku day inaad doorato aaladaha khasaaraha hooseeya;Awoodda farsamaynta awoodda si loo buuxiyo shuruudaha awoodda nidaamka.Marka loo eego shuruudaha codsiga gaarka ah, noocyo kala duwan iyo tilmaamo wareegtada waveguide ayaa la dooran karaa.
RF Waveguide Circulator waa aalad saddex-dekedood oo dadban oo khaas ah oo loo isticmaalo in lagu xakameeyo laguna hago socodka signallada ee nidaamyada RF.Shaqadeeda ugu weyn waa inay u oggolaato calaamadaha jihada gaarka ah inay gudbaan iyadoo la xannibayo calaamadaha jihada ka soo horjeeda.Dabeecaddan ayaa ka dhigaysa wareegtada inuu leeyahay qiime codsi oo muhiim ah qaabaynta nidaamka RF.
Mabda'a shaqo ee wareegiyuhu wuxuu ku salaysan yahay wareegga Faraday iyo ifafaalaha resonance magnetka ee korantada.Wareegtada, calaamaddu waxay ka soo gashaa hal deked, waxayna u socotaa jihada gaarka ah ee dekedda xigta, ugu dambeyntiina waxay ka baxdaa dekedda saddexaad.Jihada socodkani waxa ay badiyaa u jeedaan saacada ama saacada ka soo horjeeda.Haddii calaamaduhu isku dayo inuu ku faafo jihada lama filaanka ah, wareegga ayaa xannibi doona ama nuugi doona calaamadda si looga fogaado faragelinta qaybaha kale ee nidaamka ee calaamadda gadaal.
Wareegtada waveguide waa nooc gaar ah oo wareegtaha isticmaala qaab dhismeedka waveguide si uu u gudbiyo loona xakameeyo calaamadaha RF.Waveguides waa nooc gaar ah oo khadka gudbinta ah kaas oo xaddidi kara calaamadaha RF ee kanaalka jireed ee cidhiidhi ah, taas oo yareyneysa luminta calaamadaha iyo kala firdhinta.Sifadan mowjadaha mawjadaha awgood, wareegiyayaasha waveguide RF ayaa caadi ahaan awood u leh inay bixiyaan soo noqnoqoshada hawlgallada sare iyo khasaaraha calaamadaha hoose.
Codsiyada wax ku oolka ah, wareegayaasha waveguide RF waxay door muhiim ah ka ciyaaraan habab badan oo RF ah.Tusaale ahaan, nidaamka raadaarka, waxa uu ka hortagi karaa calaamadaha dhawaaqa roga ee soo noqnoqda in ay galaan gudbiyaha, si ay uga ilaaliso gudbiyaha dhaawaca.Nidaamyada isgaarsiinta, waxaa loo isticmaali karaa in lagu go'doomiyo gudbinta iyo helitaanka anteenooyinka si looga hortago in signalka la gudbiyo uu si toos ah u galo soo-dhowrka.Intaa waxaa dheer, iyada oo ay ugu wacan tahay waxqabadkeeda soo noqnoqda ee sarreeya iyo sifooyinka lumitaanka hooseeya, wareegayaasha waveguide RF ayaa sidoo kale si ballaaran loogu isticmaalaa dhinacyada sida isgaarsiinta dayax-gacmeedka, astronomy raadiyaha, iyo dardargeliyayaasha walxaha.
Si kastaba ha ahaatee, naqshadaynta iyo soo saarista wareegyada waveguide RF ayaa sidoo kale wajahaya caqabado.Marka hore, maadaama mabda'eeda shaqadu ay ku lug leedahay aragtida korantada ee adag, naqshadaynta iyo tayaynta wareegtada waxay u baahan tahay aqoon xirfadeed qoto dheer.Marka labaad, iyadoo ay ugu wacan tahay isticmaalka qaab-dhismeedka waveguide, habka wax soo saarka ee wareegga wuxuu u baahan yahay qalab sax ah oo sarreeya iyo xakamaynta tayada adag.Ugu dambayntii, maadaama deked kasta oo ka mid ah wareegga wareegga ay u baahan tahay inay si sax ah u wajahdo inta jeer ee signallada la farsamaynayo, tijaabinta iyo cilladaynta wareegga waxay sidoo kale u baahan tahay qalab xirfadeed iyo teknooloji.
Guud ahaan, wareegga waveguide RF waa qalab wax ku ool ah, la isku halayn karo, oo soo noqnoqonaya RF kaas oo door muhiim ah ka ciyaara habab badan oo RF ah.In kasta oo naqshadeynta iyo soo saarista qalabkan ay u baahan yihiin aqoon xirfadeed iyo teknooloji, iyadoo horumarka tignoolajiyada iyo kobaca baahida, waxaan filan karnaa in adeegsiga wareegyada waveguide RF ay noqon doonto mid aad u baahsan.
Naqshadeynta iyo soo saarista wareegiyeyaasha mawjadaha RF waxay u baahan yihiin injineero sax ah iyo hababka wax soo saarka si loo hubiyo in wareege kasta uu buuxiyo shuruudaha waxqabadka adag.Intaa waxaa dheer, iyadoo ay ugu wacan tahay aragtida qalafsan ee elektromagnetic-ka ee ku lug leh mabda'a shaqada ee wareegga, naqshadeynta iyo tayaynta wareegga wareegga waxay sidoo kale u baahan tahay aqoon xirfadeed qoto dheer.
