X-ray diffraction methods lie at the foundation of materials science. Determination of the crystal structures of natural minerals and, later, of crystals grown in the laboratory led to our ...

全光コンピューティングの新手法、Diffraction Castingで大規模並列論理演算が可能に 昨今の人工知能等の飛躍的な発展に伴い、GPU（Graphics Processing Unit）やTPU（Tensor Processing Unit）に代表される並列型演算器（注1）の需要が高まっています。一方で、従来の電子 ...

東京大学と早稲田大学の共同研究チームが、全光コンピューティングの新手法「Diffraction Casting」を開発しました。この画期的な技術は、大規模並列論理演算を光の速度で実行することを可能にし、人工知能（AI）や高性能コンピューティング分野に革命を ...

Diffraction refers to the bending of waves, such as light, when they encounter obstacles or pass through small openings. The size of the opening relative to the wavelength of light influences the ...

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 ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
