If your design space is extremely large or your solutions have many local extrema, then the global optimization technique discussed in this webinar may be for you.

Tune into this live demonstration with Captain Bryan Adomanis from the Air Force Institute of Technology to see how to use the COMSOL Multiphysics® software and LiveLink™ for MATLAB® to implement a particular type of global optimizer — called a genetic algorithm (GA) — into numerical simulation for design optimization.

While this process is directly applicable to a wide variety of physics and engineering problems, we will demonstrate the GA routine by optimizing the design of an optical scatterer. In this example, we will examine both a single-valued and a multivalued objective function to identify the optimal geometry of an omega particle in order to provide maximum forward scattering and minimal backward scattering.

You can ask questions at the end of the webinar during the Q & A session.

Genetic algorithm optimization of an omega particle geometry. The aim is to design a forward scatterer with minimal backscatter.

Bryan Adomanis,
Air Force Institute of Technology

Captain Bryan Adomanis earned his BS degree with high honors in physics at the University of Maryland, College Park, in 2008 and his MS in applied physics at the Air Force Institute of Technology (AFIT) in 2013. He is currently an applied physics PhD candidate at AFIT, specializing in metasurfaces in the infrared for optical applications. There, he is focusing on a 3D plasmonic design architecture. Capt. Adomanis has been in the United States Air Force for 17 years. For the past 9 years, he has conducted extensive R&D for a variety of electromagnetically engineered structures spanning RF, THz, and IR regimes, particularly in computational electromagnetics modeling and simulation for military air and space application.
