Directed diffraction without negative refraction
, 2003 Using the FDTD method, we investigate the electromagnetic propagation in two-dimensional photonic crystals, formed by parallel air cylinders in a dielectric medium.

Advanced Photonics Research, Volume 7, Issue 5, May 2026.The paper introduces the first logic gate implementation using optical metal–oxide‐semiconductor field‐effect transistor architecture, specifically designing two‐input and three‐input AND gates based on a silicene waveguide with pulse‐shaped gates. The key innovations include: (1) pulse‐shaped gate design.

Superlensing properties of one-dimensional dielectric photonic crystals
, 2009 We present the experimental observation of the superlensing effect in a slab of a one-dimensional photonic crystal made of tilted dielectric elements. We show that this flat lens can achieve subwavelength resolution in different frequency bands.

Experimental observation of Weyl points [PDF]
, 2015 In 1929, Hermann Weyl derived the massless solutions from the Dirac equation - the relativistic wave equation for electrons. Neutrinos were thought, for decades, to be Weyl fermions until the discovery of the neutrino mass.

Cherenkov Emission Generated by a Modulated Source in 2D Dispersive Photonic Crystal Slabs
Advances in Materials Science and Engineering, 2020 This work presents a systematic numerical study of Cherenkov optical radiation generated by a modulated source that moves with uniform velocity on a two-dimensional (2D) photonic crystal (PCr) slab surface.

Metasurfaces and Metadevices for Topological Electromagnetic Waves
Advanced Physics Research, Volume 5, Issue 5, May 2026.Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Efficient Color Filters Based on Fano-Like Guided-Mode Resonances in Photonic Crystal Slabs
IEEE Photonics Journal, 2018 We numerically report designs of color filters comprising of 2-D photonic crystal (2D-PhC) slabs of square lattice of air holes. The filter principle is based on excited Fano-like guided-mode resonances (GMRs) in the visible regime with high-quality ...

Chirality, Volume 38, Issue 5, May 2026.Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...

The FLAME-slab method for electromagnetic wave scattering in aperiodic slabs
, 2017 The proposed numerical method, "FLAME-slab," solves electromagnetic wave scattering problems for aperiodic slab structures by exploiting short-range regularities in these structures.
