Electromagnetics

Electromagnetics deals with the transfer of energy by radiation, such as light waves, and radio waves, and the interaction of such radiation with matter. Engineers apply electromagnetics in optical-fiber communications, radio broadcasting, wireless communications, coaxial cable systems, radar, antennas, sensors, and microwave generators and detectors, for example. Engineering researchers are examining the potential of electromagnetics in advanced computation and switching systems. Electromagnetics is one of the most analytical fields of electrical engineering in that it relies heavily on mathematics to express physical effects such as the complex relationships among electric and magnetic intensities and flux densities and material properties in space and time
