본 논문에서는 완전 전기 전도성(PEC) 물체의 정확한 모델링을 위한 교번 방향 암시적 유한 차분 시간 영역(ADI-FDTD) 방법을 기반으로 하는 무조건적으로 안정적이고 등각적인 FDTD 방식을 제시합니다. 제안된 방식은 FIT(유한 통합 기술)의 행렬-벡터 표기법 프레임워크 내에서 공식화되어 이중 그리드에서 맥스웰 방정식의 유한 차분 솔루션을 체계적이고 일관되게 확장할 수 있습니다. 2차 수렴 컨포멀 방법의 가능한 선택으로 ADI-FDTD 방법에 부분적으로 채워진 셀(PFC)과 균일하게 안정한 컨포멀(USC) 방식을 적용합니다. 제안된 컨포멀 ADI-FDTD(CADI-FDTD) 방식의 무조건적 안정성과 수렴 속도는 도파관 문제의 수치적 예를 통해 검증됩니다.

Abstract: This paper presents unconditionally stable and conformal FDTD schemes which are based on the alternating-direction implicit finite difference time domain (ADI-FDTD) method for accurate modeling of perfectly electric conducting (PEC) objects. The proposed schemes are formulated within the framework of the matrix-vector notation of the finite integration technique (FIT), which allows a systematic and consistent extension of finite difference solution of Maxwell's equations on dual grids. As possible choices of second-order convergent conformal method, we apply the partially filled cell (PFC) and the uniformly stable conformal (USC) schemes for the ADI-FDTD method. The unconditional stability and the rates of convergence of the proposed conformal ADI-FDTD (CADI-FDTD) schemes are verified by means of numerical examples of waveguide problems.
