Microwave engineering refers to the study and design of circuits, components and microwave systems. The fundamental principles are applied to the techniques of analysis, design and measurement in this field. The short wavelengths involved distinguish this discipline from electronic engineering. This is because there are different interactions with circuits, transmissions and propagation characteristics at microwave frequencies. Some theories and devices that belong to this field are antennas, radar, transmission lines, space-based systems (remote sensors), measurements, microwave radiation risks and safety measures.
During World War II, microwave engineering played an important role in the development of radars that could accurately locate enemy ships and aircraft with a focused beam of EM radiation. The fundamentals of this discipline are found in Maxwell's equations and in the work of Heinrich Hertz, the waveguide theory of William Thomson, J. Bose, the klystron of Russel and Varian Bross, as well as the contributions of Perry Spencer and others.
