Jordan Edmunds's video: Angular Spectrum and Fresnel Diffraction

https://www.patreon.com/edmundsj 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. Rather than attacking propagation directly using the Fresnel Integral, we can instead take the (much simpler) route of figuring out how *individual* plane waves propagate, and then summing them all up at the end to figure out what the electromagnetic field is some distance away. 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.
