Dr. David Keene of Georgia Southern Univeristy and Norfolk State University

Topic:

Theoretical and Computational Foundations of Metasurfaces: Enabling a Multibillion-Dollar Industry

Metasurfaces are rapidly emerging as a major photonic platform, replacing bulky optical components with compact, subwavelength-patterned layers capable of controlling amplitude, phase, and polarization. As the multibillion dollar global metasurface market continues to expand across imaging, sensing, and quantum technologies, accurate modeling and parameter extraction become critical for device design and innovation. However, conventional scalar S-parameter retrieval methods were developed for isotropic media and become fundamentally limited in anisotropic metasurfaces that exhibit polarization mixing, multi-channel propagation, and magnetoelectric coupling. In such systems, effective parameters cannot be uniquely or consistently determined using traditional refractive index and impedance extraction.
I present here, a generalized retrieval methodology based on the index-of-refraction operator formalism developed at Georgia Southern University. This operator-based framework treats metasurfaces as multi-channel systems and uses a full optical response matrix to map experimentally accessible scattering data to physically meaningful effective parameters. The method enables consistent extraction of magnetoelectric coupling channels - including Tellegen, chiral, artificial moving-medium, and omega-type couplings - even in the presence of mixed polarization and multi-mode propagation. Beyond reproducing classical limits, the framework uncovers previously unknown physical quantities that characterize electromagnetic propagation in anisotropic metasurfaces.

Biography:

Dr. David Keene grew up in South Georgia.  From humble beginnings, He achieved a Bachelor’s degree in Physics and a Master’s in Applied Physical Science from Georgia Southern University while researching theoretical plasmonics.  He went on to earn a PhD in Materials Science and Engineering from Norfolk State University with a shift to experimental plasmonics.  After a brief stint as a post-doctoral researcher at Norfolk State he went on to act as a research and development engineer for the Navy at the research center in Crane, Indiana.  He is currently working as a post-doctoral researcher at his alma matter of Georgia Southern University returning to the theoretical world.
