Learning Outcomes
Comprehension and familiarization with the concepts electromagnetic induction, the behavior of magnetic materials, the electromagnetic (time varying) field and the system of Maxwell equations, the properties and types of uniform plane waves (UPW), both for free space propagation and incidence onto plane interface between two homogeneous media. More specifically: 1. Comprehension of the development process of the induced electromotive force and the concept of mutual flux, self and mutual inductance. Introduction to time varying magnetic fields and potentials.
2. The study and understanding of the macroscopic behavior model of magnetic materials, the magnetization curve and magnetic circuits through the development of the relevant theory and examples. 3. The general electromagnetic problem, described by Maxwell's equations, boundary conditions and constitutive equations. Sources in an electromagnetic problem. Electromagnetic potentials and Lorentz gauge. 4. General equation of electromagnetic wave propagation. The concept of power flow associated with any time varying electromagnetic problem. Poynting vector and theorem. 5. Definition of the UPW, its origin and physical significance. Instantaneous value concept and complex representation of a electromagnetic quantities with harmonic time variation. UPW propagation in dielectric and conductive media. Polarization and types of a UPW. 6. Power flow associated with the UPW: Density of propagating power, Poynting vector and theorem, power loss and stored energy. Propagation toward an arbitrary direction, phase velocity and wavelength along an arbitrary direction. UPW incidence onto a flat homogeneous media plane interface. 7. Vertical/oblique incidence problems with parallel/perpendicular polarization for the various media. Reflection and refraction laws. Reflection and refraction coefficients and their computation through the Fresnel equations. Computation of specific incidence angles, polarization and critical. Total reflection problem, physical meaning, properties of a not uniform plane wave.
