Origin of TE and TM Modes

If you've felt like the content here has been helpful, please consider donating to UCI with a mention of this channel: https://give.uci.edu/ Transverse electric and transverse magnetic modes in waveguides both come from the same fundamental phenomenon - perfect reflection of a wave off an interface. This leads to a standing wave along one direction, and an electromagnetic field unlike that of a single propagating plane wave. 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.
