Spring 2021 - This class picks up where ECE 101A left off. Professor posted prerecorded lectures every week, leaving lecture time for questions. I studied primarily out of the textbook and didn't need to seriously review the lectures except for one specific topic (using transmission line model to calculate coating dimensions). Homework consisted of textbook problems, mostly fine but it's easy to overlook something and get dinged a few points. Exams were proctored on Zoom, you were allowed 1 side of 1 sheet of paper for the formula sheet on the midterm and 2 sides of 1 sheet of paper on the final. I thought the exams were alright. Most of the problems were computational but you needed to know the ideas behind the formulas to choose the appropriate one for the situation. Midterm average was around 60% and the final average was around 80%. Professor didn't say if she was going to curve or not, but I'm pretty sure she either did curve or adjusted the grade brackets, so I wouldn't panic if the raw scores don't look good. Overall I think this is a good core course if you were fine with ECE 101A and want to learn more about plane wave transmission, waveguides, and basic antennas.
