Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered ...

Fresnel Diffraction: A near-field diffraction phenomenon occurring when light encounters a phase discontinuity. Phase Step: A sudden change in the optical phase, typically due to variations in ...

A phase-steered linear array feed for a parabolic cylindrical reflector antenna is considered. The nearly cylindrical wave radiated from this line feed in the Fresnel zone is expressed in terms of the ...

Very high plane-wave reflection coefficients can be obtained with practical semiconductor quarter-wave mirrors, but for beams of finite width, the reflection coefficient of a mirror with no lateral ...

CINCINNATI — The way Bengals first-round pick Shemar Stewart fired off the line, it sounded like it could have come out of the mouth of any agent in a negotiation, NFL insider sharing ...

40/29 Meteorologist William Morrison says that shower and storm chances trend down ahead of hot and humid conditions.

Background Prior work suggests different interstitial lung diseases (ILDs) that share the radiological usual interstitial pneumonia (UIP) pattern have an overall worse prognosis. However, ...

A new study introduces a diffractive optical framework for real-time 3D and multispectral imaging, eliminating digital ...

The software ReciPro makes various crystallographic calculations, visualizes a crystal structure, simulates a diffraction pattern and high-resolution TEM image, indexes diffraction spots, plots ...
