RF and Microwave Electromagnetism

Microwave and RF elements play an important role in communication systems and due to the proliferation of radars, satellites, and mobile systems there is a need for the study of Electromagnetism. This book provides basic knowledge for the microwave and RF range. The book is intended for microwave engineers and for advanced graduate students (fourth and fifth year of university and engineers). Each of the ten chapters provides a complete analysis and modeling of the microwave structure used for emission or reception technology. We hope that this will provide to the students with a set.
