## EECS 395/495 - Special Relativity in Optics

CATALOG DESCRIPTION: This course will introduce students to Special Relativity (SR), illustrate the relation between SR and Maxwell’s Equations, and explain the origin of magentic fields and forces.  In addition, it will describe quantitatively how modern optical devices and systems such as Sagnac interferometers, gyroscopes, accelerometers, clocks and the global positioning system must take into account the effects of SR.
