I have taken an interest in microwave engineering. I found a great book: Microwave Engineering by David M. Pozar which I am going to read but I can't understand the mathematics in it. I have read nothing about physics, and I am up to a college algebra level in mathematics. My plan is to read a physics college text book and study mathematics up to calculus. Can anyone make any other suggestions as to what basics I need to learn before reading the microwave engineering book? Thanks for the help.
