The dynamical theory of diffraction describes the interaction of waves with a regular lattice. The wave fields traditionally described are X-rays, neutrons or electrons and the regular lattice are atomic crystal structures or nanometer-scale multi-layers or self-arranged systems. In a wider sense, similar treatment is related to the interaction of light with optical band-gap materials or related wave problems in acoustics. (Wikipedia).

Abstract: In this second lecture I will discuss the basic ideas of the macroscopic fluctuation theory as an effective theory in non equilibrium statistical mechanics. All the theory develops starting from a principal formula that describes the distribution at large deviations scale of the

Refraction (1 of 5) What is Refraction? An Explanation
Refraction, A conceptual qualitative explanation. Refraction is the change in direction of a ray of light as it passes from one medium to another. The amount of refraction is determined by the index of refraction of the media and the angle of incidence. For light, refraction follows Snell

Diffraction - Young's double-slit experiment with waves
Young's double-slit experiment consists in sending a wave against a wall with two parallel slits. The waves emerging from the two slits form diffraction patterns, that result from interference between these waves. This is also one of the founding experiments of quantum physics, since it wa

Diffraction from Double Slits (Young's Double Slits) [FDTD Simulation]
The double slit diffraction is illustrated via the use of finite-difference time-domain (FDTD) simulation. Two sets of double slits with different widths and a single slit - for comparison - are illuminated by normally incident plane waves. When the impinging plane waves reach the slits, t
