Electromagnetic Waves Explained: Refractive Index, Brewster Angle & Penetration Depth

How do electromagnetic waves behave when they travel through different materials? In this episode we explore the refractive index, critical angle, and Brewster angle, derive the Fresnel equations, and explain the Poynting vector for wave energy. We also cover wave attenuation in conductors, skin depth, and how frequency affects material behaviour. Perfect for students in electromagnetism, optics, or photonics. Topics: electromagnetic waves | refractive index | Brewster angle | Fresnel equations | Poynting vector | skin depth | wave attenuation.Don’t forget to follow and share the podcast with anyone that you think might profit from it, so more people can deep dive into materials engineering.Follow the podcast on ⁠Instagram⁠ and ⁠TikTok⁠ @materialsdeepdive to see the behind the scenes.
