Polarized Thermal Emission from Metamaterials Described by Stokes Parameters Based on Fluctuational Electrodynamics - Zhuomin Zhang

Explore a 42-minute conference talk on polarized thermal emission from metamaterials, delivered by Zhuomin Zhang from Georgia Tech at the Quantum and Thermal Electrodynamic Fluctuations in the Presence of Matter conference. Delve into the application of Stokes parameters based on fluctuational electrodynamics to describe thermal emission from optical metamaterials and 2D materials. Examine near-field radiative heat transfer, conventional and modified Kirchhoff's law formulations, and polarization dependence in various structures. Investigate the fluctuation-dissipation theorem, wavevector space analysis, and specific examples using hexagonal boron nitride (hBN) on glass. Gain insights into wavelength dependence, azimuthal and polar angle effects, and the implications for general Kirchhoff's law in the context of quantum and thermal electrodynamic fluctuations.
