Mufananidzo 26 unoratidza kuenzanisa pakati pemigumisiro chaiyo yekuedza uye kuenzanisa kwekushanda kwekufambisa.Chiteshi 1 uye Chiteshi 2 muMufananidzo 26a chinoenderana nekupinza uye kubuda kwezvikepe zveHFS, maererano, uye zvakaenzana nePort 1 uye Port 4 mumufananidzo 3. Mhedzisiro chaiyo yekuyera yeS11 inoyerwa zvishoma kudarika nguva yekufananidza, iyo S21 inogona kuva mhedzisiro yenguva shoma. iyo material conductivity yakaiswa mukuenzanisa yakanyanyisa uye hutsinye hwepamusoro mushure mekugadzira machining chaihwo husina kunaka.Pazvose, migumisiro yakayerwa iri muchibvumirano chakanaka nemigumisiro yekufananidza, uye bandwidth yekufambisa inosangana nezvinodiwa zve 70 GHz, iyo inosimbisa kukwanisa uye kururamisa kweiyo yakarongwa mbiri-mode SDV-TWT.Naizvozvo, yakasanganiswa pamwe chete ne-test-road-bend-road, yakasanganiswa pamwe chete ne-test-road-yakaitwa. SDV-TWT dhizaini yakatsanangurwa mupepa rino inogona kushandiswa pakugadzira inotevera uye mashandisiro.
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. Iyo chaiyo mibairo yekuyera iri muchibvumirano chakanaka nemhedzisiro yekuenzanisa.Kune yakagadzirwa maviri-danda EOS, chikamu chemasikisi uye ma electrode ekudzora zvakashandiswa pamwe chete kugadzira maviri-penzura danda.Pasi peyunifomu yakagadzirwa inotarisisa magineti, danda re electron rinogona kufambiswa zvakadzikama marefu marefu ane chimiro chakanaka.Munguva yemberi, kugadzirwa uye kuyedzwa kweEOS kuchaitwa, uye iyo yese bvunzo ichaitwa. SDV-TWT dhizaini yedhizaini inotsanangurwa mupepa rino inobatanidza zvizere tekinoroji yemazuva ano yekugadzira ndege, uye inoratidza kugona kukuru muzviratidzo zvekushanda uye kugadzirisa uye kusangana. Naizvozvo, bepa rino rinotenda kuti iyo planar chimiro ingangove iyo yekuvandudza maitiro evacuum midziyo yemagetsi mubhandi reterahertz.
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.
