Brave New World is about to hit cinemas, bringing with it the gamma-ray-powered Red Hulk. Here's what you need to know about ...

Radiation within the visible spectrum can appear black if it is low in power – more specifically, lower in power than its ...

This study introduces a multidimensional sampling theory, overcoming Nyquist limitations and enhancing metasurface design for ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

While Nyquist theory effectively defines frequency limits for ... reduced optical noise across a broad spectrum—from visible light to ultraviolet wavelengths—and demonstrated high-numerical ...

In Section 3, we describe the experimental setup and show the detected noise spectra, either the output spectrum in transmission and the homodyne detection of the mechanical motion of the two ...

Its frequency is how ... consists of photons with wavelengths spread fairly evenly across a wide range of the visible spectrum. LEDs and other electric light sources are not quite as uniform ...
