The CUET PG Physics syllabus covers topics like mathematical methods, mechanics and general properties of matter, ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

"The emission, which resembles a lighthouse beam, repeatedly sweeps past Earth as the star rotates," said lead author Mikhail Medvedev, professor of physics & astronomy at KU. "We observe this as ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

Fleischer, Applied Physics Letters107 ... Fleischer, Optics Letters 35, 2149 (2010). "Nonlinear light propagation in fractal waveguide arrays” Shu Jia and Jason W. Fleischer, Optics Express 18, 14490 ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

However, the task of designing superoscillation in optics could be a much easier ... a coherent light source it creates a complex diffraction pattern on the other side of array — a few tens ...

The diffraction limit restricts the spatial resolution of optical microscopes, making it challenging to observe structures smaller than approximately half the wavelength of the illuminating light.

Wallace Professor of Applied Physics and Vinton Hayes Senior Research ... the new interferometer has a unique, nanoscale pattern of gratings etched into the waveguide that control the energy ...

Meta-grating with a fourfold increase in efficiency At Hannover Messe, which begins Monday, March 31, Meretska and her team will present an optical diffraction meta-grating that was made using ...

Geometric optics is a confusing subject for many physics students, who often first encounter the subject in introductory college physics classes. Traditional instruction in geometric optics is not as ...

We are working to overcome these issues, particularly for tissue and biomedical ultrasound. Classical optics treats light as a smooth continuum. Quantum optics introduces new effects, and can surpass ...
