High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, EarlyView.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators

Small, EarlyView.
The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Simultaneous Acquisition of Magnetic Resonance Elastography (MRE) and Diffusion Tensor Imaging (DTI) Optimized for Human Brain

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1111-1120, September 2026.
ABSTRACT Purpose Increase clinical acceptance of MRE and DTI by shortening the scan time by half and providing diffusive and mechanical property maps that are inherently co‐registered. This proof‐of‐concept study evaluates the simultaneous DTI‐MRE acquisition in the human brain and compares its results to conventional DTI and MRE measurements.

Exceptional Light Propagation via Generalized Bulk‐Edge Correspondence

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
We show that unlike in electronic systems, localized edge states in topological photonics are governed not only by nontrivial bulk topology, but also by polarization‐dependent light‐line confinement conditions inherent to Maxwell's equations. This fundamentally generalized bulk‐edge correspondence unlocks new regimes of tunable near‐cutoff localization

A Wideband Waveguide Antenna with Nearly Equal E- and H-Plane Radiation Patterns

International Journal of Antennas and Propagation, 2013
A novel wideband waveguide antenna with excellent performance is proposed, which is composed of a coaxial-waveguide transition and an open-ended rectangular waveguide loaded with a pair of horizontal umbrella-shaped metallic brims.
