Balanis BOOK: Foundations for Microwave Engineering (McGrawHill, 1992) by Robert E. Collin 

COURSE DESCRIPTION 
This course is designed for engineers, scientists, technologists and engineering managers in the fields
of radiation, propagation, communication, navigation, radar, RF systems, remote sensing, and radio
astronomy who require a better understanding of microwave circuit analysis, design, and measurement
techniques. A basic introductory knowledge of electromagnetic theory is assumed.
