Exploring the Fascinating World of Microwave Components and Devices: An Overview

The electromagnetic spectrum is a series of frequencies ranging from radio waves to microwaves, visible light, X-rays, and gamma rays. As the wavelength of the electromagnetic radiation shortens, the waves have a higher frequency—how quickly electromagnetic waves follow each other—and therefore more energy. Radiofrequency is a type of electromagnetic …
