【摘要】：設(shè)計(jì)了一種加載集總電阻的寬帶高吸收率超材料吸波器,并且對(duì)其進(jìn)行仿真和實(shí)物測(cè)試。仿真結(jié)果顯示,該超材料吸波器在8.4~13.6 GHz的頻率范圍內(nèi)吸收率超過90%,相對(duì)吸收帶寬為47.3%;在10.3~13.1 GHz頻率范圍內(nèi)有超過99.9%的吸收率,相對(duì)吸收帶寬為23.9%。在工作頻段內(nèi),該吸波器對(duì)于寬入射角的入射波依舊能保持較高的吸收率,最后利用吸波器表面電流和電場(chǎng)分布對(duì)吸收機(jī)理進(jìn)行了分析。所設(shè)計(jì)的寬帶高吸收電磁超材料吸波器在X波段雷達(dá)、電磁隱身等方面有著巨大的潛在應(yīng)用。
[Abstract]:A broadband hyperabsorptivity supermaterial absorber loaded with lumped resistance is designed, and its simulation and physical test are carried out. The simulation results show that the absorptivity is more than 90% and the relative absorption bandwidth is 47.3% in the frequency range of 8.4 鈮，
