摘要
文章从半波损失的概念以及菲涅尔公式出发,运用图解法逐个分析了单一界面上的折射、正入射、掠入射、斜入射以及薄膜上下表面的反射与折射的半波损失问题,得出了半波损失产生的条件不仅与介质的折射率有关,还与入射角的大小有关.
Based on the concept of the half-wave loss and Fresnel formulae, this paper discusses the half-wave loss both on the refraction, normal incidence, glancing incidence and tilting incidence of the single interface and on the reflection and the refraction of the thin-film＇s both surfaces by graphic method respectively. Then the conclusion drawn from it is that the condition of producing half-wave losing is relative not only to the mediums′ refractive index but to the angle of incidence.
