Q1: Cas ua cov ntawv ci aluminium ua kom ua tau hluav taws xob tiv thaiv hluav taws xob?
A1:Aluminium ntawv ci cuam tshuam teeb meem hluav taws xob hluav taws xob tsis yog vim nws cov kev ua haujlwm siab (≈3.5 × 10 teev. Cov tawv nqaij nyhuv hluav taws xob rau cov ntug dej tsaws tsag rau saum npoo av, txhim kho kev tiv thaiv kev tiv thaiv zoo (se) ntawm ntau zaus. Nws cov nyias nyias (feem ntau 6-30μm) tso cai hloov tau yooj yim hauv multi {6} txheej txheej. Tsis zoo li cov ntaub ntawv ferrwjbetic, nws feem ntau yog tswj hluav taws xob. SE Qhov tseem ceeb ntau 60-100 dB rau 1-10 GHz cov cim.
Q2: Qhov xwm txheej dab tsi txiav txim siab tiv thaiv kev tiv thaiv kev ua tau zoo ntawm cov ntawv ci sib xyaw?
A2: Foil thickness directly correlates with SE below 18μm due to increased ohmic losses. Adhesive dielectric properties affect wave absorption in laminated structures. Surface roughness (>0.5μm) Yuav ua kom cov tsis tawm tsam tshiab tab sis txo qis kev ua haujlwm. Multilayer tsim nrog tsis- woven cov pob txha txhim kho qis- zaus (<1 MHz) performance. Optimal SE requires balancing these parameters via FEM simulation (e.g., ANSYS HFSS).
Q3: Npaum li cas yog ntawv ci tiv thaiv kev sim hauv cov qauv kev lag luam?
A3:ASTM D4935 Kev Ntsuas Se siv Coaxial Fixtures rau cov ntaub ntawv planar (0.03-1.5 GHz). Mil -} std -} 285 MOMICIT Anchoic Chamber sim rau cov conscosures. Ze li {- teb cov kev sim tshuaj ntsuam pom xau dej ntawm cov nqeg / pob qij txha hauv tiag- Lub rooj sib tham thoob ntiaj teb. Kev sim tsis muaj zog sim ua kom muaj kev co ntshav-ua rau thaiv kev tsis txaus siab. Automotive tus qauv (piv txwv li, ISO 11452) ntxiv qhov kub / av noo cycling yuav tsum tau.
Q4: Dab tsi tshwm sim cov ntawv thov tsav ntawv los ntawm kev tsim kho tshiab?
A4:6g Terahertz kev sib txuas lus xav tau ultra - Daim ntawv ci me me me me kauj. Cov khoom siv kho mob kho cov cuab yeej siv siv biocompibe ntawv nyiaj {}} polymer shields los thaiv emi. Ntse textiles ua ke woven ntawv ci xov rau cov kev tiv thaiv RF kev tiv thaiv. Satellite payloads xav tau ntawv cuav {}} Kapton Hybrids rau cov chaw tiv thaiv hluav taws xob. Cov ntawv thov no thawb Se Harbolds dhau 120 dB.
Q5: Cov ntawv ci piv rau kev tiv thaiv kab mob rau daim thaiv?
A5:Ntawv ci muab 10-15 DB ntau dua li nyiaj inks ntawm cov ntaub tuab. Sputtered txheej ua tau zoo dua tab sis raug kev txom nyem los ntawm micro - breding nyob rau hauv saj. Ntawv ci tshuab ua durability outperforms pedot zaj duab xis nyob rau hauv cov chaw hnyav. Kev Ntsuam Xyuas Tus Nqi Ntsuas Qhia Ntawv Yog 40% pheej yig dua rau loj- cheeb tsam tiv thaiv. Hybrid cov kev daws teeb meem (Ntawv ci + Conductive Adhesive) Dominate Aerospace cov ntawv thov.
