GoKawiilCOMSOL Webinar to Detail Multipole Design Method for Dielectric Metasurfaces
A webinar featuring Dr. Pavel Terekhov, a postdoctoral researcher at NIST, will explain how combining finite element simulation with multipole decomposition in COMSOL Multiphysics can predict and explain optical resonances in dielectric metasurfaces. The talk will cover a crystalline silicon metasurface built from quadrumer meta-atoms that shows enhanced absorption from two coexisting multipole mechanisms, as well as ongoing work on a gallium nitride metasurface using four interacting multipoles to control reflection, transmission, and quasi-bound-states-in-the-continuum behavior.
