A discovery could have a major impact on advancing smaller, cheaper, laser-driven particle accelerators -- and their potential applications. A discovery by University of Strathclyde researchers could ...

SIAM Journal on Applied Mathematics, Vol. 23, No. 3 (Nov., 1972), pp. 339-355 (17 pages) We discuss the diffraction of high frequency acoustic waves by a circular aperture in a plane screen. Our ...

Fig. 1 | (a) The sketch of the PDSM-241. (b) Actuator layout (clear aperture: 270mm). (c) The self-corrected aberration of PDSM-241. A new publication from Opto-Electronic Advances, ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Quarterly of Applied Mathematics, Vol. 7, No. 1 (APRIL, 1949), pp. 45-64 (20 pages) The problem of diffraction and scattering of a normally incident plane wave of sound by an infinite plane grating ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...

A sharp-edged aperture is a promising solution for eliminating side lobes from superoscillatory waves. Optical superoscillation refers to a wave packet that can oscillate locally in a frequency ...
