Photonic Doping of Epsilon‐Near‐Zero Bragg Microcavities

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Photonic doping of an epsilon‐near‐zero (ENZ) Bragg microcavity at optical frequencies induces strong magnetic responses from dielectric inclusions, enabling intense field localization, Purcell enhancement, and tunable hybrid Bragg–Mie modes. The platform supports perfect magnetic conductor and epsilon‐and‐mu‐near‐zero regimes, offering opportunities ...

Wavelength and Polarization Multiplexed Nonlocal Metasurface for Quantitative Phase Microscopy

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A nonlocal metasurface with wavelength and polarization multiplexed optical transfer functions is demonstrated for performing quantitative phase imaging. The metasurface uses the angular dispersion of optical routing guided mode resonances to extract phase gradient information along different directions for phase retrieval. ABSTRACT Imaging transparent

Dielectric-lined rectangular metal waveguide [PDF]

, 1979
The propagation characteristics of electromagnetic waves in a dielectric-lined rectangular metal waveguide have been studied. The lining on the two side walls (E-plane) together with the air space in between them is considered as a homogeneous equivalent

High‐Resolution Laser‐Induced Forward Transfer of Graphene and Graphene/hBN Heterostructures Onto SiN Photodetector Patterns

physica status solidi (a), Volume 223, Issue 13, 8 July 2026.
Laser‐Induced Forward Transfer enables the maskless, high‐resolution integration of graphene and graphene/hBN pixels onto SiN photodetector architectures. Optimized laser processing preserves graphene quality while allowing transfer down to the 15 μm scale and across complex topographies, establishing a selective, mask‐free route toward straightforward

Advanced Terahertz Sensing of Liquid Petrochemicals: Pentagonal‐Core Photonic Crystal Fiber Design and Performance

Advanced Photonics Research, Volume 7, Issue 7, July 2026.
A hybrid‐structured pentagonal‐core photonic crystal fiber sensor operating in the terahertz regime is proposed for fuel adulteration detection. Numerical analysis using the finite element method in COMSOL shows optimal performance at 2 THz, achieving high relative sensitivity (up to 98.20%) with ultralow confinement loss (~10−¹³ dB/m). The design also

Development and evaluation of an in vivo dose‐based monitoring system for electron FLASH radiation therapy

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background FLASH radiotherapy requires further preclinical and clinical investigation to establish its biological effectiveness and define optimal beam parameters. In conventional (CONV) radiotherapy, redundant beam termination systems are a cornerstone ensuring patient safety, yet analogous safeguards for FLASH delivery are not well ...

High‐Energy Topological Edge States and Strain‐Induced Multiple Flat Bands in a Honeycomb Lattice

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
This work proposes a novel anti‐twig edge in the honeycomb lattice that supports two symmetric high‐energy edge states. Moreover, the suppression or enhancement of the high‐energy edge state is observed, and strain‐induced multiple flat bands are produced.
