ECE 259H1S: Electromagnetism
Division of Engineering Science, Winter 2011-2016

The fundamental laws of electromagnetics are covered; including Coulomb's law, Gaussí law, Poisson's and Laplace's equations, the Biot-Savartís law, Ampere's law, Faraday's law, and Maxwell's equations. Vector calculus is applied to determine the relationship between the electric and magnetic fields and their sources (charges and currents). Field-matter interaction is studied, including polarization in dielectric materials and magnetization in magnetic materials. Circuit elements such as the resistor, capacitor and inductor are introduced from an electromagnetic point of view. Other topics include: electric and magnetic forces, the electric potential, capacitance and inductance, electric and magnetic energy, magnetic circuits, boundary-value problems and transmission-lines.

ECE 1229H: Advanced Antenna Theory
Fall 2003, Fall 2005

As a result of the spectacular growth in the wireless industry in recent years, research and development activity in antenna technology is more vibrant and exciting than ever. New emerging technologies include antennas for cellular mobile communications, vehicle mounted antennas, phased arrays, low profile and integrated antennas, antenna miniaturization, adaptive "smart" antennas and so on. This course provides a solid background required for any serious research work in antenna engineering for wireless applications, covering wire, resonant and aperture antennas such as dipole/monopole antennas, microstrip patch and slot antennas, horns (waveguide and integrated), lenses, parabolic reflectors. Antenna miniaturization and substrate engineering for integrated antenna design is discussed.
