The requirement for an object to be surrounded by empty space when imaged by coherent X-ray diffraction was once thought to be a fundamental limitation. A variant of coherent diffractive imaging ...

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 ...

Abstract: Metasurfaces have attracted extensive attention due to their excellent capabilities in wavefront manipulation. However, chromatic aberration, which is widely present in phase-modulated ...

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 ...
