Optical metamaterials tau npaj txhij rau kev pib ua lag luam thiab yuav txib cov lag luam muaj nqis txog ntau lab lab los ntawm 2030.

Cov ntawd yog ob qho ntawm cov kev txiav txim siab tseem ceeb ntawm daim ntawv tshaj tawm kev lag luam tshiab ntawm kev tawm tswv yim optics thiab photonics thev naus laus zis los ntawm cov kws tshuaj ntsuam ntawm Asmeskas tus kws tshaj lij Lux Tshawb.

Tus sau phau ntawv Anthony Vicari thiab Michael Holman tau hais tias kev tsim kho sai sai ntawm cov thev naus laus zis, uas siv cov kev tswj kom pom tseeb los tswj cov teeb pom kev pom, txhais tau tias kev ua lag luam yog yuav muaj tsis tau.

"Cov neeg pib loj hlob tau tsim, thiab cov lag luam loj tau nthuav qhia tseem ceeb, suav nrog kev sib koom tes, kev nqis peev, thiab cov khoom lag luam tawm los ntawm Lockheed Martin, Intel, 3M, Edmund Optics, Airbus, Cov Khoom Siv, thiab TDK," lawv hais qhia.

"Cov duab hluav taws xob ua kom zoo yuav cuam tshuam cov lag luam muag muag nyob rau lub xyoo tom ntej no," tus kws sau cov ntawv sau Vicari ntxiv. "Tsis muaj cov phiaj xwm kev tsim khoom siv thiab cov cuab yeej tsim qauv ua kom paub txog kev siv thev naus laus zis tau zoo zuj zus, tab sis cov qauv tsim thiab kev tsim khoom lag luam tau loj hlob sai heev hauv ob peb xyoos dhau los."

Kev tswj kom tiav
Thaum metamaterials tau pib ua rau muaj kev cuam tshuam rau hauv xov tooj cua thiab microwave spectrum - pab los ntawm kev tshwm sim ntawm cov ntawv thov hauv 5G tes hauj lwm - qhov nyuaj ntxiv ntawm cov tsim qauv xav tau rau kev ua haujlwm siab dua tau tuav rov qab pom lawv cov txiaj ntsig zoo li no.

Ua kom pom kev pib ua rau lub tswv yim txawv xws li "qhov pom kev pom tseeb" hauv qhov pom kev, tab sis nws muaj peev xwm ua lag luam nyob hauv ntau daim ntawv thov kev lag luam uas tau txais qhov zoo ntawm lub peev xwm los tswj lub teeb nrog kev tswj tau ntau dua li qhov ua tau nrog cov pa hluav taws xob.

Nrog rau kev tswj ntau dua ntawm cov kev taw qhia, kis tau tus mob, thiab tsom ntawm lub teeb rau txhua qhov kev ua haujlwm loj axes, cov khoom siv khoom siv hluav taws xob tuaj yeem xa cov peev xwm tshiab nrog rau kev tsis zoo, tunable, thiab cov kab ke ua kom zoo nkauj.

Lawv tseem tuaj yeem ua ke ntau lub ntsej muag kho qhov muag, xws li cov duab kho kom zoo dua qub, hauv ib txheej txheej cuab yeej, ua rau cov khoom me dua thiab sib dua.

Daim Ntawv Tshaj Qhia Kev Tshawb Fawb tau txheeb txog plaub qhov tseem ceeb uas tau txhais lub thev naus laus zis tshiab. Cov no suav nrog kev muaj peev xwm ua kom cov khoom pom kev pom zoo ntau npaum li ntuag thiab sib dua; kev siv cov qauv ntawm cov patterning rau ntau cov khoom lag luam tsim sai; wavelength-cov khoom tshwj xeeb; thiab ntau dua kev tsim kev ywj pheej.

"Optical metamaterials yuav muab qhov zoo dua rau kev ua tau zoo thiab muaj kev sib tw rau cov kev coj ua thaum ntxov uas yuav ua kom muaj kev nrawm nrawm dua thaum lawv hloov thiab ntxiv cov pa hluav taws xob," sau Vicari thiab Holman.

Lawv pom cov lag luam muaj txiaj ntsig zoo tshaj plaws tshwm sim hauv xov tooj ntawm tes lub koob yees duab thiab kho qhov muag, thiab hais tias txawm hais tias nws yuav siv sijhawm rau cov khoom siv kho qhov muag tau teev kom txog rau qhov ntau uas xav tau los ntawm cov ntawv thov, ntau ntawm cov ntawv thov me me yuav muab ntau qhov kev thov hauv lub sijhawm no.

Daim ntawv tshaj tawm tau hais tias "Txawm hais tias cov nqi tsim khoom lag luam poob nqis sai, lawv tseem siab dhau, thiab cov khoom lag luam tsawg dhau, rau ntau daim ntawv thov," "Tsis tas li ntawd, tsuas yog qee tus ntawm cov thawj coj tsim ntawm cov thev naus laus zis, uas tej zaum yuav dhau los ua qhov tsis zoo rau kev nrhav tshiab thiab kev coj mus siv hauv lub sijhawm ze."
