초록

역문제는 특히 시스템 모델링 및 모니터링과 같은 과학 및 공학분야에서 매우 흥미로운 주제이다. 역문제를 활용하면 광물자원의 탐사, 지하에 매설된 케이블 및 파이트라인 등의 동정, 의료 분야에서의 비파괴 검사 등에 응용가능하다. 본 연구에서는 먼저 2차원 전자계 산란문제를 다루고 이에 대한 FDTD법 정식화를 다룬다. 이 경우 근방계에서 관측된 데이터를 토대로 미지의 소스를 추정하기 위한 방법으로서 비선형 CGM법을 이용하였다. 본 연구에서 제안된 방법에 따른 실험결과로 볼 때 임베디드 시큐리티 모듈과 같은 원 신호 추정문제에 적용 가능할 것으로 보인다.

Inverse problem is very interest in the sciences and engineering, in particular for modeling and monitoring applications. By applying inverse problem, it can be widely used to exploration of mineral resources, identification of underground cables and buried pipelines, and diagnostic imaging in medical area. In this paper, we firstly consider 2-dimensional EM scattering problem and present the FDTD method to estimate unknown source. In this case, non-linear CGM technique is used to investigate unknown sources corresponding to measured data obtained from forward problem in near field. The proposed technique for solving the inverse source problem presents a reasonable agreement and can be applied to investigate an internal source signal of embedded security module.
