Polaritonic Critical Coupling in a Hybrid Quasi-Bound States in the Continuum Cavity-WS Monolayer System
Xia Zhang, A. Louise Bradley
We theoretically propose and numerically demonstrate that perfect feeding of a polaritonic system with full electromagnetic energy under one-port beam incidence, referred to as pol…
Absorbance Enhancement of Monolayer MoS in a Perfect Absorbing System
Xia Zhang, Julia Lawless, Jing Li +4
We reveal numerically and experimentally that dielectric resonance can enhance the absorbance and emission of monolayer MoS. By quantifying the absorbance of the Si disk resona…
Ultra-Spatiotemporal Light Confinement in Dielectric Nanocavity Metasurfaces
Xia Zhang, A. Louise Bradley
Light concentration with strong temporal and spatial confinement is crucial for tailoring light-matter interaction. Electromagnetic cavity modes in photonic and plasmonic resonator…
Wide-Angle Invisible Dielectric Metasurface Driven by Transverse Kerker Scattering
Xia Zhang, A Louise Bradley
Interference is the cornerstone of Huygens source design for reshaping and controlling scattering patterns. The conventional underpinning principle, such as for the Kerker effect,…
Constructive and Destructive Interference of Kerker-type Scattering in an Ultra-thin Silicon Huygens Metasurface
Xia Zhang, Jing Li, John F. Donegan +1
High refractive index dielectric nanoparticles have provided a new platform for exotic light manipulation through the interference of multipole modes. The Kerker effect is one exam…
A Theoretical Investigation of Decay and Energy Transfer Rates and Efficiencies Near Gold Nanospheres
Cristian A. Marocico, Xia Zhang, A. Louise Bradley
We consider the effect of Au nanospheres of subwavelength sizes on the decay and energy transfer rates of quantum systems placed in the proximity of these nanospheres. We find that…
