*Wednesday, April 25, 2012, 1:30PM, BRK 2001*: "The Art of Taming Light at the Nanoscale," Alex Kildishev, Purdue University. *NOTE*: /Dr. Kildishev is a prospective ECE Research Associate Professor candidate./ *Abstract*: This talk will review some of my recent studies, which are focused on the following topics: 1. optical metamaterials and plasmonic nanoantennas for imaging and sensing systems ? developing fast meshless solvers for modeling periodic metamaterials and metasurfaces; ? pulse shaping with metamaterials/metasurfaces; ? bi-anisotropic homogenization of optical metamaterials; 2. transformation optics concepts and applications: ? designing non-imaging gradient-index optics; ? designing and validating planar nanoplasmonic elements of diffractive optics; 3. time-domain multiphysics modeling of the periodic and random nanostructures: ? accurate modeling of dispersive plasmonic materials; ? experiment-fit modeling of stimulated emission in organic dyes. I will also cover my efforts directed towards making the modeling and optimization tools freely available to a larger research community through nanoHUB.org. *HOST: *Prof. Andrew Weiner (amw@purdue.edu<mailto:amw@purdue.edu> <mailto:amw@purdue.edu><mailto:amw@purdue.edu>; 45574)
