The principle of antenna array distribution of two-dimensional synthetic aperture microwave radiometer is presented. The optimization technique based on differential evolution algorithm (DE) is ...

A two-dimensional polymer (2DP) single crystal (T-2DP) with submillimeter size was synthesized by single-crystal to single-crystal transformation based on photochemical [2 + 2]-cycloaddition. A ...

In this letter, a near-field focused array antenna is applied to two-dimensional microwave imaging, which steers its focus on the designed focal plane by changing the operating frequency and by phase ...

The European Space Agency revealed that a mission to create an artificial eclipse was a success. The photos will allow scientists to study the sun's corona.

Constructing nanoparticles into well-defined structures at mesoscale and larger to create novel functional materials remains a challenge. Inspired by atomic epitaxial growth, we propose an “epitaxial ...
