Iinguqu zeWaveguide

I-RF waveguide, eli gama lidla ngokugubungela iintlobo ezahlukeneyo ze-hollow metal waveguides kunye ne-surface wave waveguides. Phakathi kwazo, eyokuqala ibizwa ngokuba yi-closed waveguide kuba i-electromagnetic wave eyithumelayo ivalelwe ngokupheleleyo ngaphakathi kwityhubhu yesinyithi. Eyokugqibela ikwabizwa ngokuba yi-open waveguide kuba i-electromagnetic wave eyikhokelayo ivalelwe kumda wesakhiwo se-waveguides. Ezi waveguides ze-radio frequency waveguides zidlala indima ebalulekileyo kwii-microwave ovens, ii-radar, ii-satellites zonxibelelwano, kunye nezixhobo ze-microwave radio link, apho zinoxanduva lokudibanisa ii-microwave transmitters kunye nee-receivers kwi-antennas zazo. I-Waveguide twist ikwabizwa ngokuba yi-waveguide torsion joint. Itshintsha indlela ye-polarization ngokuguqula indlela yamacala abanzi nawamxinwa kuzo zombini iziphelo, ukuze i-electromagnetic wave idlule kuyo, indlela ye-polarization itshintshe, kodwa indlela yokusasazwa ayitshintshi.
Xa udibanisa ii-millimeter wave waveguides, ukuba amacala abanzi nawamxinwa ee-waveguides ezimbini achasene, kuyimfuneko ukufaka le waveguides ejijekileyo njengenguqu. Ubude be-waveguides twist kufuneka bube yi-integer multiple ye-λ g/2, kwaye ubude obufutshane akufuneki bube ngaphantsi kwe-2 λ g (apho i-λ g ilubude be-waveguides).

Isicelo:

Ii-Waveguide twists zineendlela ezahlukeneyo zokusebenza, ikakhulu ngenxa yeempawu zazo zokusebenza okuphezulu, ezifana nesantya esiphezulu sokudluliselwa kunye nokunciphisa isignali okuphantsi, okuzenza zidlale indima ebalulekileyo emkhosini, kwi-aerospace, kunxibelelwano lwesathelayithi, kwiinkqubo zeradar, kwimifanekiso yamaza e-millimeter nakwiindawo zokufudumeza/zokupheka kwimizi-mveliso.

I-QualwaveIzixhobo ze-waveguide twists zigubungela uluhlu lwamaza afikelela kwi-110GHz, kunye neeWaveguide Twists ezenzelwe wena ngokweemfuno zabathengi. Ukuba ufuna ukubuza malunga nolwazi oluthe kratya ngemveliso, ungasithumelela i-imeyile kwaye siya kukuvuyela ukukunceda.
