Electromagnetic Theory
In this course, Maxwell's equations are applied to practical problems encountered in the design of digital electronics, communications networks, and photonics. With currents and charges as the sources of electromagnetic fields, the solutions to Maxwell's equations are pursued, subject to boundary conditions, using vector calculus, Green's function techniques and numerical simulation. The analysis of scattering of fields at normal and oblique incidence from dielectric and metal interfaces and inhomogeneous media (particles) including polarization effects provides insight into the design of devices. Subsequently, devices such as lossless and lossy transmission lines, strip-lines, metal and dielectric waveguides and cavities, optical fiber, antennas ranging from infinitesimal to linear (narrowband) to bi-conical (broadband) geometries, photonic devices such as dielectric mirrors and Fabry Perot resonators are all analyzed and strategies for their design are offered. Some of the tools the student will exercise include Smith Charts, numerical simulation, modal analysis, Bode-Fano criterion, and impedance matching techniques including quarter wave, binomial, Chebyshev transformers, single and double stub tuning. Techniques for characterization using scattering parameters will be illustrated, and the estimation of input and output scattering coefficients will also be described. This class is intended for advanced undergraduates and graduate students. Spring.
