Title: Manipulating light with metamaterials and photonic crystals

Abstract: Metamaterials are patterned materials whose electromagnetic or
acoustic properties are controlled by their internal structure. Here the
light is controlled by an internal structure that is much smaller than the
light's wavelength. A familiar example of a metamaterial is stained glass
made from gold nanoparticles. On the other hand when the internal
structure is of the same length scale as the wavelength then destructive
interference can occur giving rise to frequency intervals where no waves
can propagate inside the material. These are the well known photonic band
gap crystals; their effects include the structural coloration of butterfly
wings and they have been used in ingenious ways for optical communication.
In this lecture we provide a brief history of metamaterials and photonic
band gap crystals and a flavor of the mathematics of modeling and design.
