Diffraction is a phenomenon where electromagnetic waves (such as light waves) bend around corners to reach places which are otherwise not reachable i.e. not in the line of sight. In technical jargon such regions are also called shadowed regions (the term
Rooted in Coulomb-induced refraction, formalisms are presented to quantitatively deduce the transient surface voltages (TSVs), caused by photoinduced charge redistributions at interfaces, and are applied to examine a prototypical Si/SiO2 interface, known to be susceptible to photoinduced interfacial ...
the key components of our technique, such as the use of structured beam, the origin of the phase contrast (antiphase signals vs. refraction), experimental geometry (reflection vs. in-line imaging), as well as innate direct sensitivity to the antiferromagnetic signal are all distinctly different....
Ok, it isn't a Bragg scattering, rather refraction at a grating. Apr 13, 2014 #8 cooev769 114 0 Well that's what I was taught. It's what my textbook introduction to optical electronics and this website says, so now I'm just doubley confused. http://hyperphysics.phy-astr.gsu...

θ1 and θ2 are the incident and diffraction angles, respectively measured in the spinner substrate medium; n is the index of refraction of the spinner medium, and dx1 and dx2 are the angles by which the first and second interfaces of the spinner deviate from their ideal parallel position. ...
