Abstract: Keller introduced his Geometrical Theory of Diffraction (GTD) in the 1950s. The Geometrical Theory of Diffraction development was revolutionary, in that it explained the phenomena of wave ...

X-ray diffraction (XRD) is a powerful non-destructive analytical technique used to evaluate crystalline materials and determine their structural properties. As one of the most widely used ...

Abstract: Low-rank approximation (LRA) is a powerful technique for seismic diffraction separation and imaging, providing higher-resolution images of subsurface discontinuities compared to traditional ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Robert Kelly is managing director of XTS Energy LLC, and has more than three decades of experience as a business executive. He is a professor of economics and has raised more than $4.5 billion in ...

They say seeing is believing but our understanding of chemical systems predominantly depends on second-hand observations and measurements. A colour change can suggest that a reaction has occurred, NMR ...

Because of the neutron’s special properties, neutron diffraction may be considered one of the most powerful techniques for structure determination of crystalline and related matter. Neutrons can be ...

In 2023, AI LLM and ChatGPT were the top buzzwords, reflecting the evolving interplay between AI and big data. Concurrently, a breakthrough in overcoming the optical diffraction limit by Professor Min ...

Researchers have developed a potentially revolutionary superlens technique that once seemed impossible to see things four times smaller than even the most modern microscopes have seen before. Known as ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

Stars in the new images from the James Webb Space Telescope look sharper than they did before. And I’m not just talking about the image quality, which is astounding. I’m talking about the fact that ...
