Abstract

Principles of Dispersion Engineering in terms of control and manipulation of the signs associated with various delay terms (phase delay, group delay, and group delay dispersion) are formulated. The application of Dispersion Engineering paradigm in design of systems with negative index of refraction or negative group velocities is discussed.
