The Helmhotz equation of light beam propagating through a medium of complex refractive index is reduced to the axial-coordinate-dependent Schr?dinger equation of complex potential. The new bra vector, the new expectation value of a dynamical variable and the extended Heisenberg picture are defined ...
Advanced Mode only: controls the Beam inside intensity (when looking at the beam from the inside directly at the source). Exposure Weight (HDRP only) Use this slider to set how much effect the exposure has on the beam intensity. Scene exposure: regular Scene exposure: highExposure weight: 0....
for example, phase modulation can be achieved by slowing down the light inside the material, where the thickness of an optical neuron determines the amount of phase shift that the light beam undergoes. Alternatively
Below, we show how to generalize this 1D design heuristic to achieve 2D beam collimation and focusing in metasurface axicons and lenses, respectively. Fig. 1: Design principles for light-emitting metasurfaces. a The transmitted amplitude (blue) and relative phase (red) of a plane wave ...

We extend the scope of the Mueller calculus to parallel that established by Jones for his calculus. We find that the Stokes vector S of a light beam that propagates through a linear depolarizing anisotropic medium obeys the first-order linear differential equation dS/dz = mS, where z is the...
at an angle θ to the normal to the surface. The direction of the light beam and the normal to the surface define a planeP.Two components of the polarization vector may be considered, the so-called s-component, which is perpendicular to planeP,and the p-component, which lies in planeP....

A 3D light-field sensor was used to measure the wavefront of spherical hard X-rays (14 keV) (Supplementary Information section13). The X-ray source produces a divergent beam with a divergence angle of approximately 90° with wavefronts measured at different positions. The farther the 3D ...
