基于双负介质与负介电常数介质交叠结构的谐振腔研究
Cavity resonator based on pair of left-handed metamaterial and negative permittivity medium
【摘要】 通过探讨双负介质与负介电常数介质交叠结构的谐振特性,实现了一种能够同时缩小长度和宽度的改进的小型化谐振腔(IMCR).对IMCR谐振特性进行了数值仿真,结果表明,IMCR能够在10.3GHz上稳定谐振,但其长度和宽度却分别只有4.58和5.08mm,相比于普通金属谐振腔的长度和宽度均缩短了一半.这些结果对基于双负介质的小型化谐振腔的发展具有理论意义.
【Abstract】 The resonance property of the pair of left-handed metamaterial (LHM) and negative permittivity medium is analyzed in depth, and the results are applied to the design of an improved miniaturized cavity resonator (IMCR). The IMCR is numerically simulated, and the results show that the IMCR is resonant at 10.3?GHz while its length and width is only 4.58 and 5.08?mm, respectively, which are half that of the conventional one’s. This research may contribute in theory to the miniaturization of resonance structures based on LHM.
