Reflection of Electromagnetic Waves

This lecture discusses the reflection of electromagnetic waves, focusing on the behavior of light when interacting with different materials. It covers topics such as the Poynting vector, boundary conditions at material interfaces, and the reflection coefficient for ideal conductors and real materials with losses. The lecture also explores the concept of reflectivity under normal incidence, the role of complex dielectric constants, and the relationship between attenuation and reflectance in materials. Additionally, it delves into the reflection and refraction of light at the interface between air and glass, including Snell's law and total internal reflection.
