초록

본 논문에서는 이중 금속선으로 이루어진 다양한 곡선형 도파로를 고려하고 이 구조들에서 전파하는 모드의 특성을 수치해석적으로 분석하였다. 이중 금속선들 간의 간격과 내부 유전체의 굴절률 변화에 따라 곡선형 도파로의 최적 반경과 최소손실의 경향을 조사하였으며, 그 결과 이중 금속선 구조가 단일 금속선 구조보다 전파특성이 좋은 최적 구조가 존재함을 확인하였다.

In this paper, we analyze the characteristics of various curved waveguides composed of double metal strips using finite difference method (FDM). Our investigation reveals that the bending loss of the double metal strip waveguide can be improved with less degradation of the straight waveguide's propagation loss compared to the single metal strip structure. Optimization of the double metal strip waveguide structure has been conducted considering bending and propagation losses.
