Abstract

JEC method for Debye medium is required more memory resources and long calculation time than already well-known method such as RC method. It has been observed that JEC method would be converted to a memory effcient method by a change of discrete convolution integral range. The modified JEC method proposed here requires memory and calculation time similar to RC method, while it has a same or a smaller dispersion error than conventional methods, RC and JEC.

Debye 매질에 대한 $(FD)^2TD$ 해석에 있어 JEC(JE Convolution) 기법은 기존의 기법들보다 적은 분산 오차를 가지지만 긴 계산 시간과 추가의 메모리를 필요로 하는 단점을 지닌다. 따라서 본 논문에서는 컨볼루션의 이산적분 구간을 변경해 줌으로써 유도되는 수정된 JEC 기법을 제안하였고 그 결과 기존의 RC(Recursive Convolution)나 JEC 기법보다 적은 분산 오차를 보이는 것을 확인할 수 있었다 또한 수정된 JEC 기법 이 기존 기법들 중 가장 간단한 RC 기법과 같은 계산 복잡도와 메모리량을 요구하면서도 그보다 적은 분산 오차를 보인다는 것을 확인하였다.
