초록

본 논문에서는 무손실을 가정한 다중 전송 선로에서 전압, 전류로 결합되어 나타나는 텔레그래프(telegrapher) 방정식의 시간 영역 Closed-form 해석해를 EP(Explicit Propagator) 방법을 이용하여 구하였다. 전송 선로에서 전압과 전류를 정확하게 얻기 위한 시간 영역의 표현식을 얻었으며, 본 논문의 결과를 검증하기 위하여 대칭 결합스트립 선로, 선형 테이퍼 형태의 비균일 결합 스트립 선로 그리고 삼중 비대칭 스트립 선로에 대한 과도 응답 특성을 구하고 상용 소프트웨어 결과와 비교하였다. 본 논문에서 개발된 시간 영역의 수치 해석 방법은 균일, 비균일 또는 대칭, 비대칭 스트립 선로의 시간 영역 파형에 대해 매우 정확한 결과를 보여주며, 다양한 결합 선로의 해석에 유용하게 사용할 수 있다.

Time domain closed-form analytical solutions to the coupled telegrapher's equations for the voltage and current on a lossless multiconductor transmission line are presented. The resulting expressions are obtained in the form of exact time domain propagators operating on the line voltage and current. Time domain numerical methods are developed and examples showing exceptionally accurate results are obtained for uniform and nonuniform; symmetric and asymmetric strip lines.
