Sib koom tes hauv tsev WiFi thiab tsis muaj peev xwm xauj hauv lub xov tooj thaum kev sib txuas lus txhua hnub nyob tom qab kev sib txuas lus hauv lub tswv yim thev naus laus zis. Tam sim no, metamistersion Inantennas hauv chav kuaj nyob hauv cov kev sib txuas lus, kho cov kev sib txuas lus tsim kho kom muaj kev lag luam tawm tshiab, los ntawm 5G lub chaw nres tsheb rau cov khoom siv hluav taws xob.

I. Txheej Txheem Txheej Txheem: Tsim Cov Khoom Siv
Kev cuam tshuam kev cuam tshuam ntawm kev ua metamis txwv tshuaj tiv thaiv pib nrog kev rov ua dua ntawm "qhov chaw ntawm kev ua tau zoo."
Tsis zoo li cov kav hlau txais xov uas cia siab rau cov tshuaj zoo li tooj liab zoo li tooj liab thiab txhuas (ession}
Kev tshawb fawb ntawm Profess Wang Wang Hong pab pawg ntawm kev tshawb fawb txog cov qauv kev qhia no: lawv tsim cov kev qhia ua lej uas muaj peev xwm twv txiaj ntsig zoo thiab tswj hwm lub dielectric tas li ntawm cov khoom.
Cov micro no - units, me dua nyob rau hauv loj thiab spacing system "rau lub teeb liab" kev ua kom muaj kev ua kom ua tau nrog cov khoom ntuj.
Lub zog ntawm cov qauv txheej txheem no tshwj xeeb yog muaj pov thawj nyob rau hauv ntau zaus band kev pab them nqi.

Pab neeg tau muab txoj kev pab tau tag nrho x -}} {} {}}}}}}}}}}}}}}}}}}}}}}}}}} 4.2 GHz rau cov kav hlau txais xov. Nyob rau hauv qhov kev txiav ntau tshaj - ntug terahertz teb, kev sib xyaw ua ke nyob rau ntau zaus qhib kev sib txuas lus ntawm 0.47-1.1 qhov kev sib txuas lus siab "
Ii. Reconfigurable Technology: Ua tus kav hlau txais "kev hloov pauv uas xav tau"
Yog tias cov qauv tsim qauv yog lub hauv paus ntawm MetSitision Antennas, tom qab ntawd lawv deformancion thiab reconfigurability yog lawv feem ntau cov kev lom zem tshaj plaws. Ib pab neeg ntawm MIT tau tsim cov tshuaj tiv thaiv me me uas nws ua tau zoo tuaj yeem hloov kho los ntawm cov kav hlau txais xov thaum ib yam "ib hom, ib lub neej."
Cov tub ntxhais tsis pub lwm tus paub txog cov kav hlau txais xov hauv cov kev tsim qauv ntawm nws cov geometry. Pab pawg thawj coj Marwa Alalawi piav txog, "Tus qauv tshwj xeeb ntawm kev ua metamaterials tuaj yeem txo cov kev nyuaj ntawm cov tshuab khoom siv." Los ntawm kev khiav haujlwm yooj yim xws li khoov, ncab, lossis cov tshuaj tiv thaiv, cov kav hlau txais xov tuaj yeem hloov nws cov khoom lag luam ib zaug kom tau sib txuas nrog ntau cov qauv kev sib txuas lus. Tests show that the prototype's resonant frequency shift can reach 2.6%, sufficient to support headphones switching between different modes, and it still functions normally after 10,000 deformations.
Kev tshoov siab los ntawm origami, reconfigurable metasurfaces txuas ntxiv pom qhov peev xwm rau kev tswj kev siv zog. Los ntawm kev ua tiav ob - qhov seem rau peb {}} Txoj cai ntawm cov kev ua haujlwm nyob rau hauv kev ua haujlwm hauv tsev kawm ntawv qib siab. ib puag ncig.
III. Los ntawm kev kuaj cov khoom lag luam: cov ntawv thov kev siv ua kom methent antennas tsis yog ib lub tswv yim; Lawv tau pom muaj txiaj ntsig zoo xws li kev sib txuas lus thiab tshuaj, thiab tseem muaj txawm tias cov khoom lag luam hluav taws xob.

Hauv kev sib txuas lus kev sib txuas lus, nws tau dhau los ua tus "tsis pom kev cuam tshuam" rau kev ua haujlwm nrawm ntawm 5g tes hauj lwm. Tus Clubent Dielectric tas li Metoriction Metorna Tsim los ntawm Wang Hong tau ua tiav qhov kev ua tau zoo tab sis kuj txhim kho hluav taws xob ua tau zoo thiab ua ntu zus.

Dielectric tus thawj tswj kav hlau txais xov los ntawm tus tsim qauv dielectric tas li
Tom qab Nokia saws a substrate nrog cov kev siv thev naus laus zis hauv Munich, lub nroog hluav taws kub tau nce los ntawm 800Mbps rau 1.2GB.
Ntawm lub davhlau ya ua khoom siv sab nraud, lub metamis lees cov kab mob sib koom tes tsim los ntawm Lenovo thiab 6G band ntawm qhov teeb meem yoga ntawm 10}} hlau rov qab them rau cov khoom.
Daim ntawv thov ntawm Terahertz Band tau qhib txawm tias muaj ntau dua cov peev xwm tshiab. Researchers have developed metamaterial antennas using Kapton and quartz fabric as substrates and single-walled carbon nanotubes as conductive materials. Cov kav hlau txais xov no yog 0.47 {{{4 4}} 1.1 Thz zaus daws teeb meem, tsis yog- kev ua kom puas tsuaj, thiab lwm daim teb. Wang Hong pawg neeg kuj tau ua tiav cov kev sib tsoo hauv cov khoom thermal tswj. Lawv cov boron nitride -} Kev daws qhov hluav taws xob ntawm 42}} Qhov tsawg ntawm cov cua sov dissipation bottipation bottipation
IV. Kev tsim kho kom tawg: txav los ntawm precision tsim rau cov kev nce qib loj hauv kev tsim cov thev naus laus zis hauv kev nqa metamater rau kev sim ua lag luam. Kev ua kom tiav ntawm 3D luam ntawv tshuab tau ua rau cov qauv replication ntawm cov microstructures ua tau.
Wang Hong pab pawg tau siv ncaj qha -}}}}}}}}}}}}}}}} ov kev ntsuas dielrical tas li thiab kwv yees tseem ceeb rau hauv 5%. Qhov siab siab - precision kev lag luam paves txoj kev rau customized kav hlau txais xov. Pab neeg mit, txawm li cas los xij, txhim kho cov txheej txheem sib txawv, tsim cov txheej txheem sib txuas ua ke laser txiav thiab cov tshuaj tsuag, nrog rau cov qauv tsim qauv. Cov neeg siv tuaj yeem kho rau lub antennas rau lawv cov kev xav tau tshwj xeeb, tseem txo qis kev tsim cov nyom.
Hauv cov ntawv thov muaj kev lag luam, qhov txheej txheem kev tsim qauv no ua kom muaj txiaj ntsig zoo dua. ZTE pib chaw siv metamators sib xyaw ua cua sov dissipation modules, ua hauj lwm txheej txheej kub ntawm 72 degree} txoj kev tswj hwm kom ruaj khov los ntawm 18% hauv kev daws teeb meem rau 3%. Ib tug huawei pib chaw nres tsheb qauv, tom qab npaj txhij pi {{6} Cov nqi thauj mus los ntawm 806kg, txo qis kev thauj mus los ntawm 25% thaum nce ntxiv los ntawm 40%. Cov kev sib tsoo no ua rau pom tias qhov loj- nplai thov ntawm metam ntaub ntawv tiv thaiv muaj qhov tseeb ntawm lub hauv paus.
V. Yav Tom Ntej Lub Zeem Muag: Kav hlau txais xov raws li "cov chav nyob sib luag"
Nrog txoj kev hloov zuj zus ntawm 5G thiab kev tshawb fawb ntawm 6g kev tshawb fawb, metam ntaub ntawv ntawm kev hloov pauv hloov mus rau hauv "Cov cuab yeej muaj peev xwm" uas tuaj yeem hloov kho tau lawv ib puag ncig. Cov kws tshawb nrhiav tau ua haujlwm ntawm peb - seem} qhov seem ntawm cov qauv, ua kom nws hloov kho cov xwm txheej ntau dua.
Rov qab ua kom txaus siab thiab lub tunability tau ua kom pom tseeb kev qhia. MIT lub Allormable kav hlau txais xov tuaj yeem sib xyaw rau hauv cov khoom lag luam txhua hnub: thiab yav tom ntej, lub tswv yim ntawm "khoov rau lub xov tooj kom paub meej. Ntawm lub hauv paus chaw nres tsheb qib, fluorinated PI films txo cov khoom siv cov dielectric tas li rau 2.8@100GHz, paving txoj kev rau 6G Terahertz kev sib txuas lus.
Los ntawm cov qauv qauv hauv chav kuaj kom siv cov khoom siv hluav taws xob, nrog lawv cov qauv kev ua tau zoo, "tau tawg ntawm kev sib txuas lus qab nthab ntawm wireless sib txuas lus ntawm wireless kev sib txuas lus. Thaum precision tsim raws kev tsim khoom tshaj plaws, cov teeb meem teeb meem uas ib zaug plagned peb yuav maj mam ploj mus, thiab nrawm dua wireless wireless yog nyob rau lub qab ntug.
