Abstract

We implemented double-negative metamaterials using cross-polarized split-ring resonators in a microstripline. The split-ring resonators comprised quad ring structures and were connected with the microstripline in series. Four different structures, with the shorted rings in varying locations, were fabricated to demonstrate reconfigurable band-pass characteristics. The effective permittivities and permeabilities were extracted using the Ziolkowski method. Excellent agreement between the developed circuit model and the measurement was observed up to 10 GHz.

본 논문에서는 마이크로 스트립 선로로 구성된 Split Ring Resonator (SRR) 구조를 이용하여 대역통과 필터를 설계하였다. 설계된 필터는 metamaterial 구조이며, 두 개의 공진주파수를 갖는다. SRR은 마이크로 스트립 선로에 삽입된 4개의 SRR 구조로 설계 되었다. 각각의 SRR은 가상 스위치 동작에 의해 4개의 state를 가지며, Switch의 ON/OFF동작에 따라 주파수 재구성 특성을 보이는 대역 통과 공진기를 설계하였다. 공진기의 전자기적 특성을 설명하기 위해 Ziolkowski 방법으로 유전율과 투자율을 계산하였다.
