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 between ...

Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered phase ...

Researchers from the Institute for Materials Research at Tohoku University, in collaboration with the Japan Atomic Energy Agency and the RIKEN Center for Emergent Matter Science, have identified a new ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

(Nanowerk News) A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices. The research was led by ...
