MIC505 Electromagnetics And Applications (core course)

Instructor: Dr. Marcus Dahlem
Pre-requisites: Basic calculus and differential equations.
Next time offered:  Spring 2014

Brief Description:

Electromagnetics is essential for understanding key concepts in electronics, photonics and micro-electromechanical systems. This course explores electromagnetic phenomena in modern applications, including wireless and optical communications, circuits, computer interconnects and peripherals, microwave communications and radar, antennas, sensors, micro-electromechanical systems, and power generation and transmission. Fundamentals include quasistatic and dynamic solutions to Maxwell's equations; waves, radiation, and diffraction; coupling to media and structures; guided waves; resonance; acoustic analogs; and forces, power, and energy.
