RF and Microwave Engineering

RF and Microwave Engineering involves the study and design of "circuit-based technical materials" that operate in the radio frequency (RF) and microwave spectrum, typically from 300 MHz to 300 GHz. It focuses on the "logical" behavior of high-frequency signals where traditional circuit theory is replaced by wave propagation and transmission line theory.
