Abstract The miniaturization of photonic technologies calls for a deliberate integration of diverse materials to enable novel functionalities in chip-scale devices. Topological photonic systems are a promising platform to couple structured light with

Abstract Topological phases of matter have been attracting significant attention across diverse fields, from inherently quantum systems to classical photonic and acoustic metamaterials. In photonics, topological phases offer resilience and bring nove

The primary challenge for long-wavelength infrared (λ = 8–13 µm) detection has long been the mitigation of dark current while achieving a high conversion efficiency of optical to electrical signals. Often overlooked is the bandwidth of detector r

The neocortex encodes complex and simple motor outputs in all mammalian species that have been tested. Given that changes in neocortical reorganization (and corresponding corticospinal output) have been implicated in long term motor recovery after st

Abstract This study considers optimizing the planform of wind turbine blades to ultimately enhance wind plant controls, namely, wake steering strategies. Adjoint‐enabled unsteady actuator line simulations are carried out to obtain gradients for opt

A method for measuring carrier dynamics in micron-scale optoelectronic materials based on time-resolved microwave reflection is reported. Compared to a standard time-resolved photoluminescence approach, the authors show a 105 improvement in sensitivi

Monocrystalline metallic nanoparticles are preferable for plasmonic applications, but grow only in polyhedral shapes, which deviate from the predominantly employed spherical shape. Through numerical simulations we have investigated possibilities for

Recently, III-V semiconductor nanowires have been widely explored as promising candidates for high-performance photodetectors due to their one-dimensional morphology, direct and tunable bandgap, as well as unique optical and electrical properties. He

The complexity of urban systems makes it difficult to adequately address their changes using a model based on a single approach. In this research, we developed a GIS-based integrated approach to modeling and prediction of urban growth in terms of lan
