AI Article Synopsis

  • The paper discusses electromagnetic scattering from a periodic array of circular cylinders, focusing on a scenario where some cylinders are missing.
  • It presents a formulation using the recursive transition-matrix algorithm (RTMA), which is effective for analyzing the scattering from a finite number of cylinders.
  • The research introduces a pseudo-periodic Fourier transform to enhance the RTMA alongside a technique called lattice sums, proposing a novel spectral-domain approach to address the complexities of periodic cylinder arrays with defects.

Article Abstract

This paper considers the two-dimensional electromagnetic scattering from periodic array of circular cylinders in which some cylinders are removed, and presents a formulation based on the recursive transition-matrix algorithm (RTMA). The RTMA was originally developed as an accurate approach to the scattering problem of a finite number of cylinders, and an approach to the problem of periodic cylinder array was then developed with the help of the lattice sums technique. This paper introduces the concept of the pseudo-periodic Fourier transform to the RTMA with the lattice sums technique, and proposes a spectral-domain approach to the problem of periodic cylinder array with defects.

Enhancing photoluminescence (PL) efficiency in colloidal quantum dots is pivotal for next-generation near-infrared photodetectors, imaging systems, and photonic devices. Conventional methods, especially metal-based plasmonic structures, suffer from large optical losses, which limits their practical use. Here, we introduce a quasi-bound state in the continuum (quasi-BIC) metasurface on a silicon-on-insulator platform, tailored to provide high-quality factor resonances with minimized losses.

Microtextured microneedles are tiny needle-like structures with micron-scale microtextures, and the drugs stored in the microtextures can be released after entering the skin to achieve the effect of precise drug delivery. In this study, the skin substitution model of Ogden's hyperelastic model and the microneedle array and microtexture models with different geometrical parameters were selected to simulate and analyse the flow of the microtexture microneedle arrays penetrating the skin by the finite-element method, and the length of the microneedles was determined to be 200 μm, the width 160 μm, and the value of the gaps was determined to be 420 μm. A four-pronged cone was chosen as the shape of microneedles, and a rectangle was chosen as the shape of the drug-carrying microneedle.

Fish in the wild often contend with complex flows that are produced by natural and artificial structures. Research into fish interactions with turbulence often investigates metrics such as turbulent kinetic energy (TKE) or fish positional location, with less focus on the specific interactions between vortex organization and body swimming kinematics. Here, we compared the swimming kinematics of rainbow trout (Oncorhynchus mykiss) holding station in flows produced by two different 3×5 cylinder arrays.

Article Synopsis
  • Dielectric metasurfaces with quasi-bound states in the continuum (qBICs) can boost field enhancement through narrow resonances in the visible and near-infrared ranges.
  • A new silicon-on-silica metasurface design supports up to four qBIC resonances by using an elliptical cylinder array with varied symmetry-breaking shapes.
  • The study showcases the nonlinear process of four-wave mixing and highlights the potential applications in areas like information multiplexing and multi-wavelength sensing using the unique geometric control of qBICs.

Article Synopsis
  • - The study aimed to create a novel conformal elliptical-cylinder resonator, called MICER, to improve wrist MRI scans at 1.5 T and assess its clinical utility.
  • - Researchers compared MICER with a traditional 12-channel wrist coil using various MRI sequences and analyzed images from a phantom and 14 wrists of healthy volunteers, focusing on image quality metrics like signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR).
  • - Results showed that MICER provided significantly better SNR and CNR for wrist tissues compared to the 12-channel wrist coil, suggesting its promising role in enhancing MRI quality in clinical settings.
