Seminar Title: Optimization By Email of 3D Plasmonic Crystal Structures
Speaker: Sven Leyffer, MCS
Date/Time: 2009-09-09 15:00
Location: Building 221 Conference Room A261
Description:
We study the refractive index sensitive transmission of a 3D
plasmonic crystal, which can exhibit strong optical responses near certain wavelengths and are used in chemical sensing applications. Our goal is to design a a square array of subwavelength cylindrical nanowells in a polymer conformally coated with a gold film that maximizes the optical response.
Every choice of design parameters requires the solution of a 3D finite-difference time-domain simulations that runs for 12 hours of wall-clock time on a 125-nopde linux cluster. We reveal ‘How the Optimization Was Won’ using low-tech tools such as email, matlab, and AMPL.
