Electromagnetics E4411: Engineering Electromagnetics The interaction of electromagnetic fields with more complicated media (such as anisotropic) provides insight for a wide range of practical devices such as modulators, electromagnetic shields and isolators. The topic of radiation is thoroughly studied in order to understand how electromagnetic signals are generated and propagated, and the workings of an antenna serve as an example. After understanding propagation, scattering of electromagnetic waves from various metallic surface shapes can be examined. An example of the use of these concepts would be electromagnetic interference generated from traces on printed circuit boards or switched-mode power supplies, where it is often necessary to reduce or control this typically unwanted interference. Students taking the engineering electromagnetics course will learn how electromagnetic devices ranging from antennas to microwave ovens to optical fibers operate. The application of the principles learned are therefore very broad, impacting industries and products such as cell phones, radars, computers, and communication links of all kinds. It is important for students to have a mastery of beginning electromagnetics, complex numbers and phasors, vector calculus, and differential equations. EE4441/EE4490: Laser Systems and Applications EE4441, The Laser, provides a thorough introduction in the fundamentals of lasers. The quantum physics of energy levels, transition rates, population inversion, and gain are given to provide the student with an understanding of the design and operation of a laser sufficient for industrial and commercial applications. The gain equation is presented along with issues of amplification and loss within the laser cavity. Examples of many types of lasers are given, from gas lasers, to dye and solid-state lasers and their relative strengths and weaknesses presented. In addition to the fundamentals of how a laser functions, the unique attributes of the laser beam, particularly coherence length, is discussed. Interferometry using a laser is used to illustrate the advantage it represents for making sensitive measurements of position, for example. Although a background in quantum physics is desirable for EE4441, it is not required and the necessary concepts will be given. However, a background in beginning electromagnetics is assumed, as well as differential equations and complex number Antenna Design: In recent fall semesters, Antenna Design has been offered under the ECE Special Topics course number EE4800.
