Hello, I'm Ben

I am a researcher and software developer.

About me

My research is mainly focused on wave physics including metamaterials, scattering, diffraction, modal analysis, numerical methods, topology optimization, resonant phenomena, Transformation Optics and homogenization techniques, for applications in Photonics and Mechanics.
