Quasinormal Coupled Mode Theory
Hanwen Zhang, Owen D. Miller
Coupled mode theory (CMT) is a powerful framework for decomposing interactions between electromagnetic waves and scattering bodies into resonances and their couplings with power-ca…
Minimum Dielectric-Resonator Mode Volumes
Qingqing Zhao, Lang Zhang, Owen D. Miller
We show that global lower bounds to the mode volume of a dielectric resonator can be computed via Lagrangian duality. State-of-the-art designs rely on sharp tips, but such structur…
Computational bounds to light-matter interactions via local conservation laws
Zeyu Kuang, Owen D. Miller
We develop a computational framework for identifying bounds to light-matter interactions, originating from polarization-current-based formulations of local conservation laws embedd…
Optimal materials for maximum near-field radiative heat transfer
Lang Zhang, Owen D. Miller
We consider the space of all causal bulk materials, 2D materials, and metamaterials for maximum near-field radiative heat transfer (RHT). Causality constrains the bandwidth over wh…
Tight Bounds on the Effective Complex Permittivity of Isotropic Composites and Related Problems
Christian Kern, Owen D. Miller, Graeme W. Milton
Almost four decades ago, Bergman and Milton independently showed that the isotropic effective electric permittivity of a two-phase composite material with a given volume fraction i…
Approaching the upper limits of the local density of states via optimized metallic cavities
Wenjie Yao, Mohammed Benzaouia, Owen D. Miller +1
By computational optimization of air-void cavities in metallic substrates, we show that the local density of states (LDOS) can reach within a factor of of recent theor…
