Uhlobo olutsha lwe-terahertz i-Corahertz inomgangatho wedatha kabini kunye nokuphuculwa ngokudibeneyo kwe-6G ngokudibeneyo kunye nokulahleka kwe-bandwidth kunye nelahleko ephantsi.
Abaphandi bazise iqela le-terahertz eninzi ephindaphindiweyo ephinda-phinda ubungakanani bedatha kunye nokuzisa inkqubela phambili yotshintsho kwi-6G nangaphaya. (Umthombo weMifanekiso: Imifanekiso yeGetty)
Unxibelelwano olulandelayo olungenazingcingo, lumelwe yitekhnoloji ye-terahertz, kuthembisa ukuguqula usulelo lwedatha.
Ezi nkqubo zisebenza kwi-terahertz frequency, zifundisa i-bandwidth engekho ntshona yosulelo lwedatha ye-Ultra ngokukhawuleza. Nangona kunjalo, ukuqaphela ngokupheleleyo le miceli mngeni enokubakho, ebalulekileyo yobuchwephesha kufuneka yoyiswe, ngakumbi ekulawuleni nasekusebenziseni i-spectrium ekhoyo.
Inkqubela phambili ehlazekileyo ithe yalungisa lo mngeni: I-Ultra yokuqala ye-Ultra ye-Ultra ye-Ulrahert Perahert
Ezi zinto zoyilo oluyintshayelelo i-Sub-Terahert J Bit (220-330 GHZ) kwaye ijolise kunxibelelwano lwe-6G nangaphaya. Isixhobo sinokuphinda-phinda ubungakanani bedatha yedatha ngelixa sigcina ireyithi yendawo yokulahleka ephantsi, ihambisa indlela yeenethiwekhi ezingenazingcingo eziphakamileyo.
Iqela elisemva kwe-proimestone libandakanya i-prondom ye-verisnet gonhaasandkomeni ukusuka kwiYunivesithi yaseAdelaide yoMbuso kwiYunivesithi yaseOsaka, ngoku iNjindini yaseMasayuki fujita.
Unjingalwazi WighayandkonkmSul uxele imithombo yedatha emininzi ukuba idluliselwe ngaxeshanye ngaphakathi kwibhendi ethe tyaba, ephindaphindiweyo ngokufanelekileyo. I-bandwidth efunyenwe sisixhobo ingazange ibonwe ngaphambili nangaphaya koluhlu oluzayo, elimele i-quap ebalulekileyo yee-alxes ezihlanganisiweyo.
I-Politsic Aunticys ibalulekile kunxibelelwano lwale mihla njengoko benza ukuba imiqondiso emininzi yokwabelana nge-frequency eqhelekileyo, ephucula kakhulu amandla ejelo.
Esi sixhobo sitsha sikuphumelela oku ngokusebenzisa abatshatisi be-commance kunye ne-anisotropic edibeneyo. Ezi macandelo zandisa i-polifering birfricringEnce, ekhokelela kumyinge wokupheliswa komgangatho ophucukileyo (kwi-PER) kunye ne-bandwidth-eyona mpawu ziphambili zeenkqubo zonxibelelwano ezifanelekileyo ze-terahert.
Ngokungafaniyo noyilo lwemveli oluthembelela kwi-Asymmency Wavemeric waveegides, i-Aulticmer entsha isebenzisa ukuhambisa i-anisotropic ukuxhomekeka kuxhomekeko kuphela. Le ndlela igcina ngokupheleleyo i-bandwidy eyaneleyo enikezwe ngabatshati abatshatileyo.
Isiphumo sisiseko se-bandwidth esisondeleyo kufutshane ne-40%, i-avareji nganye kwi-20 dB, kunye nelahleko yokufakelwa ubuncinci belahleko ye-1 DB. Ezi metrics zentsebenzo zigqwesileyo zigqwesileyo zezoyilo kunye ne-microwave ye-microwave, ezihlala zinengxaki yebhendi emxinwa kunye nelahleko ephezulu.
Umsebenzi weqela loPhando akaphumi nje ukusebenza kweenkqubo ze-teraherz kodwa ikwabeka isiseko sexesha elitsha kunxibelelwano olungenazingcingo. UGqr. Izicelo ziquka ukuhambisa inkcazo yevidiyo, ikhutshiwe inyani, kunye neenethiwekhi ezilandelayo zeselfowuni njenge-6g.
Isisombululo semveli seTerahert porilact porilization, enjenge-Orthogonal Dradricers (OMTS) esekwe kwi-avembander yentsimbi enxantathu, ebusweni. Isinyithi samava amava anyusa ilahleko ephakameni, kwaye iinkqubo zabo zemveliso zintsokothile ngenxa yeemfuno zejometri.
I-Opecial Politmers Auntsyers, kubandakanya abo basebenzisa i-Mandu-Zeender Priestors okanye i-Fomatonic Crystals, zinike i-Photoniki engcono kunye nokulahleka okusezantsi kodwa zihlala zifuna urhwebo phakathi kwe-bandwidth, ukungcola, kunye nokwenza ubushushu.
Abatshatisi abatshatileyo basetyenziswa ngokubanzi kwiinkqubo ze-optical kwaye bafuna i-polilization yobuqili i-birfrielince yokufezekisa ubungakanani be-compact kunye nephezulu. Nangona kunjalo, zinomda womngxunya ocekeceke kunye nobuntununtunu ekuqinisekiseni ukungangqinelani.
I-CounterXint entsha idibanisa izibonelelo zokudibanisa abatshatileyo kunye nokuvala okusebenzayo okusebenzayo, ukoyisa kwale mida. Ukugquma kwe-anisotropic kubonisa ukuba i-bireringer enkulu, iqinisekisa phezulu kwi-bandwidth ebanzi. Lo mgaqo woyilo uphawula ukuhamba kwiindlela zemveli, ukubonelela ngesisombululo esiyingqongqo kunye nesisebenzayo somdibaniso weTerahert.
Ukuqinisekiswa kovavanyo lwe-CounterXers kuqinisekisile ukusebenza kwayo okhethekileyo. Ifowuni isebenza ngokufanelekileyo kwi-225-30 GHZ i-GHZ, iphumeze i-bandwidth enenxalenye ye-37.8% ngelixa ugcina i-20 DB. Ubungakanani bayo obuhlanganisiweyo kunye nokungqinelana kweenkqubo zemveliso ezisemgangathweni zenza ilungele ukuveliswa kwesininzi.

Izicelo ezinokubakho zale teknoloji zidlulela ngaphaya kweenkqubo zonxibelelwano. Ngokuphucula ukusetyenziswa kwe-spectrum, i-CounterXer inokuqhuba inkqubela phambili kwimihlaba efana ne-radar, icinga, kunye ne-Intanethi yezinto. "Kwisithuba seminyaka elishumi, silindele ukuba obu buchwephesha be-terahertz ukwamkelwa ngokubanzi kwaye buhlanganiswe kumashishini ahlukeneyo," unjingalwazi u-WighasandkonKul watsho.
I-CounterXer ikwadityaniswa ne-wangermy yezixhobo ezinomthumo eziphuhliswe liqela, ukunika amandla onxibelelwano ekugxilwe kuzo kwiqonga elidityanisiweyo. Oku kuhambelana nokugxininisa ekusebenziseni kunye nokunganyamezeleka kweqonga le-Dolectric WaveGide.
Iziphumo zophando zeqela zipapashiwe kwijenali laser kunye noPhononongo lwePotonic, ezigxininisa ukubaluleka kwabo ekuqhubeleni phambili kwitekhnoloji ye-pherahertz ye-teratoic ye-pherahertz. Unjingalwazi uFujita waphinda wathi, "Ngokwayisa izithintelo zobugcisa ezibaluleke kakhulu, oku kulindeleke ukuba kuphucule umdla kunye nomsebenzi wophando ebaleni."
Abaphandi balindele ukuba umsebenzi wabo uya kuphendulela izicelo ezitsha kunye nokuqhubela phambili ukuphuculwa kobuchwephesha kule minyaka izayo, ekugqibeleni kukhokelela kwiiprototypes zorhwebo kunye neemveliso.
Le mulxer imele inyathelo elibalulekileyo phambili ekuvuleni amandla onxibelelwano lwe-terahertz. Ibeka imigangatho emitsha yezixhobo ezidibeneyo ze-terahert kunye ne-metriti yayo engazange ibonwe ngaphambili.
Njengoko imfuno yesantya esiphezulu, uthungelwano oluninzi lwamandla luyaqhubeka lukhula, ezi zinto zinokutsha ziza kudlala indima ebalulekileyo ekwenzeni ikamva letekhnoloji engenazingcingo.
