Enhanced Light-Matter Interactions in Dielectric Nanostructures via Machine Learning Approach
Lei Xu, Mohsen Rahmani, Yixuan Ma +9
A key concept underlying the specific functionalities of metasurfaces, i.e. arrays of subwavelength nanoparticles, is the use of constituent components to shape the wavefront of th…
Pushing the Limit of High-Q Mode of a Single Subwavelength Dielectric Nanocavity
Lujun Huang, Lei Xu, Mohsen Rahmani +2
High index dielectric nanostructure supports different types of resonant modes. However, it is very challenging to achieve high-Q factor in a single subwavelength dielectric nanore…
Accurate metasurface synthesis incorporating near-field coupling effects
Andreas E. Olk, David A. Powell
One of the most promising metasurface architectures for the microwave and terahertz frequency ranges consists of three patterned metallic layers separated by dielectrics. Such meta…
Extreme defect sensitivity from large synthetic dimensionality
Lukas J. Maczewsky, Kai Wang, Alexander A. Dovgiy +7
The geometric dimensionality of a physical system significantly impacts its fundamental characteristics. While experiments are fundamentally limited to the maximum of three spatial…
