Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

open access: yesAdvanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.

Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics

open access: yesAdvanced Optical Materials, EarlyView.
Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.

Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities

open access: yesAdvanced Photonics Research, EarlyView.
We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing
