Abstract

In this paper, several diffraction formulas are discussed and diffraction losses predicted from each formula for a wedge are compared with each other. Simulation results are also compared with measured ones. It turns out that in real situations, where many scatterers are located around a diffracting wedge, the prediction from the simple knife-edge formula for vertical polarization agrees well with the measured loss.

본 논문에서는 대표적인 희절공식들을 살펴보고, 쐐기 형태의 구조물에 대한 희절손실 예측치를 비교해 모았다. 또한 시뮬레이션 결과를 측정치와 비교, 분석하였다. 은 산란체가 의절체 부근에 존재하는 실제 환경에서 수직편파에 대한 의절손실은 단순한 knife-edge 공식이 측정치와 잘 일치하였다. 일치하였다.
