The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...
X-ray crystallography is a technique used to reveal how the atoms of crystalline solids are arranged, relying upon the diffraction of X-ray radiation by the periodic atomic structure. Its continual ...
A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
Abstract: Metasurfaces have attracted extensive attention due to their excellent capabilities in wavefront manipulation. However, chromatic aberration, which is widely present in phase-modulated ...
One of the most important and critical problems in materials science is determining the crystal structure or structures of a given material. The positions that ions occupy in the unit cell of a ...
An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core. Kanazawa gold leaf is a ...
Abstract: The side wall diffraction has been studied in elongated rectangular and tapered anechoic chambers at VHF/UHF bands. Methods for diffraction reduction were suggested. The concept of side wall ...
