Wave impedance is a concept central to acoustics, mechanics, electromagnetics, and optics. In this video I describe wave impedance in terms of electromagnetics, as a ratio between the electric and the magnetic field of a traveling plane wave. If you know the electric field, amplitude, you know the magnetic field amplitude, and vice-versa.
If you liked this video and are feeling like an awesome person, please meander over to my patreon at / edmundsj to support more of these videos!
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.
