초록

본 논문은 무조건 안정의 특징을 갖는 ADI-FDTD의 특성을 효과적으로 적용하기 위한 가변 분해능 시간 영역 전자파 해석법을 제안한다. 제안된 해석법은 관심 주파수 영역에서 정확도를 유지하면서 분해 시간 간격을 증가시켜 계산 시간을 감소시킬 수 있다.

To make the best use of known characteristics of the alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method such as unconditional stability and modeling accuracy, an efficient time domain solution with variable time-step size is proposed. Numerical experiment shows that a time-step size for a given mesh size can be increased preserving a desired numerical accuracy over frequencies of interest. The proposed method can be used to analyze electromagnetic problems with reduced computation time.
