The EM‐waves can strike the interface of two media with different electrical characteristics, either normally or obliquely. If the second medium is a dielectric medium, the waves undergo both reflection and transmission, whereas if the second medium is a perfect conductor, the reflection occurs. The obliquely incident plane waves follow the well‐known Snell's law (also called Snell-Descartes law) of reflection and refraction. There are important applications of obliquely incident EM‐waves.
