In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

IN a series of experiments now in progress, we are directing a narrow beam of electrons normally against a target cut from a single crystal of nickel, and are measuring the intensity of scattering ...

Photonic Crystal Fibers (PCFs) represent one of the most successful and impactful applications of photonic crystals. These specialized optical fibers incorporate a microstructured arrangement of ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...
