Summary (2-4 sentences)<br>Just a few informal sentences describing what you want to present.<br>No need to spend a lot of time on this! You can change it later.

In this talk, we will discuss the potential value of a metasurface to serve as a ‘laser sail’ for a recently proposed relativistic spacecraft. Metasurfaces consist of sub-wavelength structures that dramatically alter –in a controlled manner—the optical properties of the material. Simulating large, complex metasurfaces can be done using Finite Difference Time Domain (FDTD) simulations, but these require significant computing power, limiting the number of parameters that can be explored. We will show how High Throughput Computing provided an alternative pathway to analyze the behavior of >10,000 variations on the ‘laser sail’ without the use of FDTD simulations. The best behaved ‘laser sails’ could then be examined in more detail using the FDTD simulations.

Availability of the Speaker<br>Let us know if there are times you CANNOT present,<br>prehaps because you need to leave for the airport early, etc.
