Microwave Engineering Notes Questions and Answers part 1
Here i am sharing 2 marks microwave engineering notes. 1. Define Microwave. Microwaves are generally described as electromagnetic waves with frequencies that range from approximately 1GHz to 1000 GHz. Therefore, microwave signals, because of their inherently high frequencies, have relatively short...
