I am currently taking ECE203, which is electromagnetic waves. For the past weeks we were talking about polarizations of the EM waves. Professor kept repeating linear polarization and circular polarizations. I am confused, and I went to YouTube to see if there is any videos for illustrations. I found a great video.
I love this 3D representation of the linear and circular polarization. This helps me a lot in understanding the materials. YouTube actually have a lot of cool videos. Especially for a course like ECE203, it is really helpful to actually see how plane wave move in a 3 dimension.
