Ultrasensitive Tunable Terahertz Sensor via Critical Coupling‐Enhanced Fano Resonance

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This work presents a hybrid terahertz sensor via the combination of graphene‐strip metasurface, cavity resonance, and gold film polaritons. The sensor achieves critical coupling with an ultrahigh‐Q resonance and tunable FOM with stable high sensitivity via gate voltage regulation, exhibiting excellent performance for on‐chip integrated biochemical ...

Broadband and Wide‐Angle Nonreciprocal Electromagnetic Transport via Gradient Permeability‐Near‐Zero Metastructures

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
ABSTRACT Breaking time‐reversal symmetry to achieve broadband and wide‐angle nonreciprocity is critical in electromagnetic waves manipulation. While Epsilon‐Near‐Zero materials have revolutionized the control of Transverse Magnetic modes, realizing comparable broadband nonreciprocity for Transverse Electric (TE) modes remains a formidable challenge ...

Long‐Range Polariton Canalization in a Graphene‐Nanoribbon–Covered MgTeMoO6 Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Simulated Re(Ez) field distributions at ω = 924 cm−1 for the graphene grating, MgTeMoO6 grating, the proposed hybrid structure, and the corresponding IFCs in (kx, ky) space are shown. Re(Ez) field maps in the x–y plane at ω = 924 cm−1 for Ef = 50, 70, 74, 76, 80, and 88 meV.

Spectropolarimetric Holographic Multiplexing Metasurface With Super‐High Capacity Empowered by Mechanical Rotation

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Mechanically reconfigurable metasurfaces enable high‐capacity optical storage and holography due to low cost/complexity. A differentiable inverse design framework maps meta‐atom geometries to multichannel optical responses via deep neural networks. Rotatable cascaded metasurfaces optimized through this pipeline achieve pixel‐level holography with 288 ...

Terahertz Encryption With a Polarization‐Sensitive Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...
