Abstract

This paper presents the new Compact 2D Haar-wavelet-based MultiResolution Time-Domain method (MRTD) as an accelerating algorithm for the conventional Compact BD Finite-Difference Time-Domain method (FDTD). To validate this algorithm, we analyzed the dispersion characteristics of the hollow rectangular waveguide and dielectric slab-loaded rectangular waveguide. The results of the proposed method are very weal agreed with those of both the conventional analytic method and the Compact 2D FDTD method. The CPU time for analysis of this method is reduced to about a half of the conventional Compact 2D FDTD method. The proposed method is valuable as a fast algorithm in the research of dispersion characteristics of waveguide structures.

본 논문에서는 기존의 Compact 2D FDTD(Finite-Difference Time-Domain)에 대한 고속화 알고리즘으로써 Haar 웨이블릿 기반 Compact 2D MRTD(MultiResolution Time-Domain) 차분식을 제안하였다. 구현된 알고리즘을 이용하여 내부가 공기로 태워져 있는 구형 도과관과 포과관 내부치 일부가 유전체로 채워져 있는 구형 도파관을 해석하였다. 본 논문의 결과는 기존의 Compact 2D FDTD치 결과 및 해석적인 해와 매우 잘 일치한다. 또한 계산 소요시간이 기존의 Compact 2D FDTD에 비해 절반 가까이 절약되었음을 확인하였다. 제안된 알고리즘은 도파관 구조의 분산 특성 연구에 있어 효율적인 고속화 기술로서 의미가 있다고 할 수 있다.
