Abstract: In this paper, we investigate the electromagnetic diffraction characteristics of 3D perfect electric conductor (PEC) parallel circular double disks illuminated by a Hertzian dipole with ...

Researchers at Lawrence Berkeley National Laboratory have developed a 4D-STEM workflow that can isolate and solve atomic structures from individual nanocrystals buried inside dense, tangled clusters, ...

Five years ago, mathematicians Dawei Chen and Quentin Gendron were trying to untangle a difficult area of algebraic geometry involving differentials, elements of calculus used to measure distance ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Abstract: To overcome the challenge of balancing high performance with low manufacturing cost in large-aperture compact antenna test range (CATR) systems, this letter proposes and validates a novel ...

For "Laser wavelength", the colors in the gradient and the dot does not match. For both "Laser wavelength" and "Grating line density", the range of the slider UI is not clear.

(a) Working principle of metasurface displacement measurement can be understood as the detection of the power of different modes of the converted light. The incident irradiated on the metasurface and ...

For a compact crossover, the Honda HR-V is pretty impressive. It's relatively affordable — the MSRP on a 2026 HR-V starts around $26,000 — and gets decent gas mileage. Leather details, thoughtful ...

Entrepreneurs who build successful businesses often possess a unique ability to see what others don't—the critical bottlenecks hiding in plain sight that create frustration, inefficiency, and lost ...

Word problems try and tell students a story about the math problem in front of them. They are a useful way to connect abstract numbers to concrete situations, so students can learn early on to apply ...
