Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical domain, not only are superlenses a promising choice: concepts such as super-oscillations could provide ...

Abstract: The intelligent omni-surface (IOS) is a dynamic metasurface that has recently been proposed to achieve full-dimensional communications by realizing the dual function of anomalous reflection ...
