"EngNotes" are my engineering notes. This is my way of creating a digital version of an engineering notebook. This particular entry is on Polarization.
Textbooks and online references often don't give a complete and practical discussion of how to calculate the impact of a wave's polarization on the magnitude and phase of a received signal. As a result, I made a polarization toolbox for Matlab to serve as a quick reference. There is a link to the toolbox in the Code section below.

The best practical resource on polarization I have found
