Augmented reality smart glasses impose an unusually severe set of requirements on a display. The image source must be physically small enough to fit inside a temple or frame, bright enough to remain visible against the…

Scientific computing underwent a structural change when researchers stopped treating computation as a machine they had to own and began treating it as a service they could request. Programmable cloud laboratories propose…
Keywords are a small component of a research manuscript, but they perform several important functions. They help journal submission systems classify a paper, support editor and reviewer assignment, contribute to…
Artificial intelligence models trained on simulation data are increasingly used as surrogate models for finite element analysis, computational fluid dynamics, molecular simulation, photonic design, structural mechanics,…
Machine learning is increasingly being presented as a new computational engine for physics and engineering. Physics informed neural networks, Fourier neural operators, DeepONets, graph based operator models, and related…

Ansys vs COMSOL in 2026
Selecting between Ansys and COMSOL in 2026 is not a matter of identifying a universally superior finite element package. Both platforms can solve demanding engineering problems, both support multiphysics analysis, and…
Photonic crystal fibers present a deceptively difficult electromagnetic modeling problem. Their cross-sections may appear to be simple arrangements of air holes in glass, yet the optical behavior emerges from several interacting length scales, strong refractive-index discontinuities, wavelength-dependent material properties, and radiation into an effectively unbounded exterior domain. Small numerical errors can therefore propagate into large […]
Prism-based surface plasmon resonance sensors are widely used for detecting small changes in the refractive index of liquids, gases, biological layers, and functional coatings. Their apparent structural simplicity can be misleading. A conventional Kretschmann sensor may contain only a prism, a thin metallic film, and an analyte, yet its predicted resonance angle, minimum reflectance, linewidth, […]
Introduction The optical spectrum of a photonic device is the measurable consequence of a complex interaction among geometry, material dispersion, electromagnetic boundary conditions, excitation state, fabrication variability, and environmental conditions. Whether the device is a wavelength-selective filter, metasurface, photonic crystal cavity, grating coupler, resonator, optical sensor, or nonlinear waveguide, its functional behavior is often summarized […]
In academic publishing, the labels Q1 and Q2 describe a journal’s relative position within a defined subject category. The letter “Q” stands for quartile, meaning that journals are ranked according to a selected bibliometric indicator and then divided into four approximately equal groups. Q1 contains the highest-ranked group, Q2 contains the next-highest group, Q3 contains […]
