無備註
1. This is an ENGLISH (or bi-lingual) course. International students, exchange students, and non-EE-background students are all welcome to attend. 2. You are expected to attend each class to get a better sense on how to prepare for the exams.
1. Final score = midterm 1 + midterm 2 + final exam, and you should expect NO adjustment or finesse on the final score. (三次考試分數相加, 不調分) 2. The exams will NOT be restricted to materials covered in the textbooks or reference books. (考試內容不限於課本/參考書) 3. Closed-book with NO cheating sheet. (閉書考試, 無大抄可帶)

1. Field and Wave Electromagnetics by D. K. Cheng will be used as one reference book, though it is pretty difficult to read and understand. 2. Fundamentals of Applied Electromagnetics by Ulaby adopts a much more interesting approach by starting with the transmission line application, and is the second reference. 3. No course-pack. (無上課講義)
