Electromagnetic Fields

An introduction to transmission lines: voltage and current waves, characteristic impedance, reflections from the load and source, transients on a transmission line, Smith's chart, impedance matching. Fundamentals of electromagnetic theory: Maxwell's equations, boundary conditions, wave equation and its solutions in lossless and lossy media. Constitutive relations and dispersion. Plane wave propagation, reflection and transmission at boundaries. Waveguides; propagating and evanescent waveguide modes and cut-off frequencies. Introduction to radiation and antennas.
