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 ...

New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction has been achieved using a nano-patterned array of ferromagnets. This demonstration arises from a unique interaction ...

The magnetic nanoscale array can be thought of as a specialized grating that the waves go through. To their surprise, instead of the typical symmetric diffraction pattern, the research team ...

Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 ...

As SAWs traveled through the structured magnetic array, it functioned as a diffraction grating, altering the wave propagation characteristics. The results showed a nonreciprocal diffraction ...

Once thought impossible, quasicrystals revealed a hidden order that challenges our understanding of materials. Their ...

Detailed in a paper just published in the journal Optics Express, the experimental setup uses a tellurium-doped fiber laser ...

The short answer is; no. We will never see atoms using visible light, simply because the wavelength of visible light (around 400 to 700 nanometers) is larger than the size of an atom (around 0.1 to ...

Photonic crystal surface-emitting lasers or PCSELs are laser diodes that generate laser beams through controlled light wave interaction within a photonic crystal structure. In a recent study, ...

‘Wave analysis’ refers to a group of techniques that provide valuable insight into these interactions by scrutinizing the shape of blood pressure and flow/velocity waveforms. The aim of this review ...
