초록

무한 도체평판에 있는 슬롯과 무한히 긴 가는 도선간의 전자기적인 결합문제를 MPIE(mixed potential integ gral equation)와 세분된 기저함수를 사용하는 2차원 모벤트법으로 해석하였다. 또한 폭이 좁은 슬롯의 경우에 타당한 중심표현법(center -representation)을 이용하여 동가회로를 구하였다. TM 편파된 평면파가 슬롯에 임의의 각으로 입사하는 경우에 슬롯에서의 등가자기전류와 도선에 유도된 전류를 구하였다. 그리고 도선과 무한 도체평판으로 구성된 전송선로에 전류를 인가할 때, 슬롯에 의한 전송선로의 반사계수 및 투과계수를 구하고 실험치와 비교하여 잘 일치함을 확인하였다.

The problem of electromagnetic coupling into a thin conducting wire through a slot in an infinite conducting is analyzed by use of MPIE(mixed potential integral equation) and two- dimensional moment method using subsectional(rooftop) basis functions. The equivalent circuit is derived using a center-repesentation method which is valid in a narrow slot case. The equi- valent magnetic currents on the slot and the induced currents on the wire are caculated respec- tively, for the TM wave is incident upon the slot with arbitrary angle of incidence. The theoretical transmission coefficients of transmission line which is composed of thin-wire and infinite conducting plate with a narrow slot are compared and found to be in good agreement with experimental results.
