Engineering Multipole Resonances in Dielectric Metasurfaces

IEEE Spectrum is hosting a webinar featuring Dr. Pavel Terekhov from the National Institute of Standards and Technology, focusing on the design and simulation of dielectric metasurfaces. These structures are becoming essential in nanophotonics for their ability to control light properties like amplitude, phase, and polarization. The session will demonstrate how to use COMSOL Multiphysics software to perform multipole decomposition, allowing researchers to predict and manipulate optical resonances. Dr. Terekhov will discuss the evolution of quadrumer meta-atoms and their application in silicon and gallium nitride metasurfaces to achieve anomalous absorption and quasi-bound-states-in-the-continuum (q-BIC). By connecting full-wave simulations with analytical insights, the presentation aims to provide engineers with a robust strategy for designing advanced optical devices for sensing and energy harvesting. This webinar offers a practical look at turning complex resonance behaviors into actionable design rules for next-generation flat optics.
