Provides a grounding in the physics behind the operational principles of high frequency technologies. The text presents up-to-date methods, as well as the research and developments of more efficient devices for use in applications, from mobile and satellite communications and wireless Local Area Networks to energy transformation and sensors. Examples and theories support the material.
