I must say, these are excellent videos!! I am currently taking online courses in a RF engineering certificate at UCSD and your explainations are covering the same material but are more easily understood. Please continue to produce more videos.
Hello Professor Smith, I am confused about backward propagating and the reflected wave/energy. According to the wave equations, the electric signal consist of 2 components: forward and backward propagating components. In the case of reflection, is the backward propagation equal to reflected wave? Or, are there forward, backward propagating signal and a reflected signal? And one more question: when it is applied voltage from a source, do forward and backward waves start to propagate at the same time? I mean the forward wave starts from source side and the backward wave starts from load side at the same time, right? I am trying to imagine what is going on but it's hard to understand. Thank you for these wonderfull videos!
The total solution to the wave equation includes the possibility of propagation in both directions (a backward propagating wave and a forward propagating wave). That does not mean that both are always present. If excitation happens at one end of the line, you will initially only have forward propagation. If that forward-propagating wave encounters an impedance mismatch, a part of its energy will reflect, resulting in a backward-propagating wave.

Extremely oraganised and simple. Straight to the point. Thanks for posting
High quality content. Thanks!
I just saw the full series. It's fantastic and very well explained.
These videos are just fantastic. Thank you and great job, Professor Smith!
Thank you!

Thank you for the feedback! I appreciate it!
That was a nice, no nonsense treatment of (a part of) the subject. And well presented too. Thanks.
Thank you, Professor!!!
Hi! Can I have access to homework problems, and the textbook that is being followed in this lecture series.?

is it possible to have a list of the order in which to watch the playlists. I am new to RF and using your video playlist i really appreciate your work
beautifully explained .. thank you maam!!
Thank You KLS
