If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible.

In this video, I introduce the concept of 'boundary conditions' - or how the electromagnetic fields in one material affect the adjacent fields in a different material. I use Faraday's Law to derive an equation relating the tangential electric fields between the two materials.

This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.

Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.
