Hyperbolic Surface Exciton Polaritons and Surface Waves in Near‐Zero Permittivity Regions Supported by Artificial Organic Hyperbolic Metamaterials

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
A fully organic route to artificial hyperbolic metamaterials is introduced, utilizing multilayered thin films of J‐aggregate dyes. These structures exhibit strong optical anisotropy, experimentally supporting hyperbolic surface exciton polaritons and surface waves in near‐zero Permittivity regions.

Parity-Time Symmetric Nonlocal Metasurfaces: All-Angle Negative Refraction and Volumetric Imaging

Physical Review X, 2016
Lens design for focusing and imaging has been optimized through centuries of developments; however, conventional lenses, even in their most ideal realizations, still suffer from fundamental limitations, such as limits in resolution and the presence of ...

Design of Large‐Aperture Hybrid Refractive Metalens System

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

An active viscoelastic metamaterial for isolation applications

, 2014
Metamaterials are of interest due to their ability to produce novel acoustic behaviour beyond that seen in naturally occurring media. Of particular interest is the appearance of band gaps which lead to very high levels of attenuation within narrow ...

From Molecular Design to Optical Anisotropy: Orientation Control in BODIPY Langmuir‐Blodgett Films

Advanced Optical Materials, Volume 14, Issue 33, 4 September 2026.
The supramolecular organization of amphiphilic boron‐dipyrromethene (BODIPY) dyes in Langmuir–Blodgett monolayers is shown to govern their optical anisotropy. By correlating nanoscale imaging and angle‐resolved spectroscopy, we reveal symmetry‐driven control of transition dipole orientation, enabling either in‐plane or out‐of‐plane optical responses ...
