Maxmizing Band Gaps in 2-D Photonic Crystals

308 , Mathematics Research Center Building (ori. New Math. Bldg.)

Photonic crystals are periodic structures composed of dielectric materials, and designed to exhibit band gaps which are of great interest for many important applications. In this talk I will introduce the generalized gradient which is used in optimization when the target function is non-smooth, and seek to produce maximal band gap by optimization based evolution algorithm.
