Figure 1: Calculated peak reflectivity, interaction length and reflection energy bandwidth for X-rays in Bragg backscattering from diamond for all allowed reflections with Bragg energies E H up to 30 ...

Ultrahigh-reflectance mirrors are essential optical elements of the most sophisticated optical instruments devised over the entire frequency spectrum. In the X-ray regime, super-polished mirrors with ...

Snow accumulation on the Peninsulas and western Southside kept temperatures cooler this week, illustrating albedo's role in local weather and climate.

Two weeks ago, I talked about an introduction to radar and how it works on a basic level. This time, we are looking into radar reflectivity specifically, the most popular product of weather radar.

Scientists in Hong Kong have demonstrated a new ultra-white ceramic material that can drastically cool buildings by reflecting sunlight and heat at record highs. The beetle-inspired material gets its ...

Precipitation intensity is measured by a ground-based radar that bounces radar waves off of precipitation. The Local Radar base reflectivity product is a display of echo intensity (reflectivity) ...

Earth is literally losing some of its shine. New readings from NASA’s long‑running satellite missions show that the planet is reflecting slightly less sunlight back into space, a subtle shift that ...

Since May 24, 2019, SpaceX has been launching satellites into orbit 60 at a time to bolster the ranks of its Starlink megaconstellation – a fleet of networked sats flying in formation that, once ...

A new study examines structural buckling as a control method for solar sails, detailing kirigami cuts, simulations, and experiments to adjust spacecraft orientation efficiently.

Hot and arid climates benefit most from the combination of agriculture and PV farms. Image: Iberdrola. Combining solar modules and crops in an area is not a new idea in the PV industry since it could ...

A high reflectivity mirror, also known as a supermirror, is a dielectric mirror that has been carefully designed to provide optimal reflectivity while minimizing any scatter and absorption effects.
