Quasistatic oscillations in subwavelength particles: Can one observe energy eigenstates? [PDF]
, 2018 In increasing the capabilities of the optical and microwave techniques further into the subwavelength regime, quasistatic resonant structures has attracted considerable interest. Electromagnetic responses of electrostatic (ES) plasmon resonances in optics and magnetostatic (MS) magnon resonances in microwaves give rise to a strong enhancement of local ...

Multi-wavelength focusing based on nanoholes
New Journal of Physics, 2020 A kind of controllable multi-wavelength focusing metalenses is proposed. The proposed metalenses consist of identical nanometer holes etched in silver film and the beam focusing at three primary wavelengths is controlled without additional phase ...

Broadband Chiroptics with Twist‐stacked Hyperbolic Conducting Polymer Thin Films
Advanced Materials, EarlyView.Anisotropic conducting polymer films can exhibit optical hyperbolic properties which here are found connected to large birefringence and linear dichroism. Off‐axis twist‐stacking of only two such subwavelength films can therefore enable large and broadband circular dichroism (CD), with CD bandwidth closely related to the hyperbolic bandwidth. The study
