Izvo zviyero zvekuyera zveS11 zvishoma zvishoma kudarika nguva yekufananidza. mukuenzanisa kwakanyanyisa uye kushata kwepamusoro mushure mekugadzira machining kwakashata.Pazvose, migumisiro yakayerwa iri muchibvumirano chakanaka nemigumisiro yekufananidza, uye bandwidth yekufambisa inosangana nezvinodiwa zve 70 GHz, iyo inosimbisa kukwanisa uye kurongeka kweiyo yakarongwa mbiri-modhi SDV-TWT. Naizvozvo, yakasanganiswa neiyo chaiyoiyo yekugadzira nzira yekugadzira TWra-SD dhizaini dhizaini yeSDVra-SDT dhizaini yedhizaini iyi. bepa rinogona kushandiswa kugadzira kunotevera uye maapplication.
Mupepa iri, dhizaini yakadzama yekugovera planar 220 GHz dual-beam SDV-TWT inoratidzwa.Kusanganiswa kweiyo mbiri-modhi yekushanda uye mbiri-beam excitation inowedzera kuwedzera kushanda bandwidth uye kubuda simba.Kugadzira uye kutonhora bvunzo kunoitwa kuti kuone kana HFS yese.Mhedzisiro chaiyo yekuyera iri muchibvumirano chakanaka nemigumisiro yekufananidza.Kune EOS yakagadzirwa maviri-danda, chikamu chemasikisi uye magetsi ekugadzirisa zvakashandiswa pamwe chete kugadzira danda repenzura maviri.Pasi peyunifomu yakagadzirwa inotarisa magnetic field, bhanhire re electron rinogona kuendeswa kune marefu marefu ane chimiro chakanaka.Munguva yemberi, kugadzirwa nekuedzwa kweEOS kuchaitwa, uye TWSD mal test ichaitwa, uye TWSD mal test ichaitwa. mupepa rino rinonyatsobatanidza teknolojia yekugadzira ndege yemazuva ano, uye inoratidza kukwanisa kukuru muzviratidzo zvekushanda uye kugadzirisa uye kuungana.Naizvozvo, pepa iri rinotenda kuti urongwa hwemapurani hunonyanya kuve hutsika hwekuvandudza kwevacuum electronic devices mubhandi re terahertz.
Ruzhinji rwe data raw uye analytical modhi muchidzidzo ichi zvakabatanidzwa mune ino bepa.Rumwe ruzivo rwakakodzera runogona kuwanikwa kubva kumunyori anowirirana pane chikumbiro chine musoro.
