A High-Performance Parallel FDTD Method Enhanced by Using SSE Instruction Set

International Journal of Antennas and Propagation, 2012
We introduce a hardware acceleration technique for the parallel finite difference time domain (FDTD) method using the SSE (streaming (single instruction multiple data) SIMD extensions) instruction set.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Full-Wave Analysis of the Shielding Effectiveness of Thin Graphene Sheets with the 3D Unidirectionally Collocated HIE-FDTD Method

International Journal of Antennas and Propagation, 2017
Graphene-based electrical components are inherently multiscale, which poses a real challenge for finite-difference time-domain (FDTD) solvers due to the stringent time step upper bound. Here, a unidirectionally collocated hybrid implicit-explicit (UCHIE)

Label‐Free SERS Fingerprinting of Neuroprotein Conformational Dynamics in Human Saliva

Advanced Materials, EarlyView.
Galvanic molecular entrapment (GME) is a label‐free method for detecting and quantifying neuroprotein conformational states. This technique enables direct surface binding and in situ hotspot generation around molecules, effectively overcoming challenges related to target localization and mismatched hotspot geometries.

Domain Decomposition CN-FDTD with Unsplit-Field PML for Time-Reversed Channel Analysis [PDF]

Radioengineering, 2018
In this paper, an efficient domain decomposition (DD) technique is introduced into the implicit Crank-Nicolson finite-difference time-domain (CN-FDTD) method to analyze the channel characteristics of time reversal (TR) waves. As an unconditionally stable

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

Advanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

Formation of Laser‐Induced Periodic Surface Structures on Titanium Alloy Using a Picosecond Laser: Dependence on Fluence and Number of Laser Pulses

Advanced Materials Interfaces, EarlyView.
Laser treatment of materials is a versatile technique for generating ordered surface structures. Nevertheless, such structures are the result of laser parameters such as laser pulse fluence. We demonstrate that homogeneous low special frequency laser‐induced periodic surface structures are contingent on both single and effective fluence dose and can be
