基于全介质棒状结构Mie杂化耦合原理的带通滤波器
Bandpass filter based on Mie hybrid coupled resonance in rod-type all-dielectric structures
摘要
Abstract
By using high-permittivity and low-loss dielectric rod-type metamaterials, a bandpass filter was realized in microwave ranges. The first magnetic resonance and the first electric resonance overlaped in the same frequency range. The hybrid coupled resonance leads to an enhanced transmission in the X-band (8-12 GHz), suggesting good bandpass filter performance. By carefully designing the arrangement of rods, a good filtering effect was got. When further simulating the five dielectric rod-type structures, the filter has a central frequency of 9.4 GHz, a 3 dB bandwidth of 532 MHz, and an insertion loss of about 2 dB with a very steep attenuation in outside of the pass band.关键词
