Non-Gaussian statistics of optical near-fields
1College of Optics and Photonics/CREOL, University of Central Florida, Orlando, FL 32816, USA.
Summary
Scattered light intensity from random media can follow Gaussian or non-Gaussian patterns. Non-Gaussian patterns in reflection-emission setups reveal information about the interface, aiding in physical interface characterization.
Area of Science:
- * Optics
- * Condensed Matter Physics
- * Wave Scattering
Background:
- * Optical fields near random media are modeled as superpositions of waves with random phases.
- * Understanding the statistical properties of scattered light is crucial for characterizing random media.
Purpose of the Study:
- * To investigate the statistical regimes (Gaussian and non-Gaussian) of scattered light intensity.
- * To explore the potential of using these statistics for interface characterization.
Main Methods:
- * Theoretical modeling of optical fields interacting with random media.
- * Analysis of scattered intensity statistics under different experimental geometries.
- * Focus on a reflection-emission configuration.
Main Results:
- * Demonstrated that both Gaussian and non-Gaussian intensity statistics can be established.
- * Showed that the first-order statistics of scattered light are non-Gaussian in a reflection-emission configuration.
- * Confirmed that non-Gaussian statistics can be used to retrieve interface information.
Conclusions:
- * The statistical behavior of scattered light depends on the experimental geometry.
- * Non-Gaussian statistics in reflection-emission setups offer a novel method for probing physical interfaces.

01:26Gauss's Law: Spherical Symmetry
A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if the system is rotated, it doesn't look different. For instance, if a sphere of radius R is uniformly charged with charge density ρ0, then the distribution has spherical symmetry. On the other hand, if a sphere of radius R is charged so that the top half of the sphere has a uniform charge density ρ1 and the bottom half has a uniform...
01:07Gauss's Law
If a closed surface does not have any charge inside where an electric field line can terminate, then the electric field line entering the surface at one point must necessarily exit at some other point of the surface. Therefore, if a closed surface does not have any charges inside the enclosed volume, then the electric flux through the surface is zero. What happens to the electric flux if there are some charges inside the enclosed volume? Gauss's law gives a quantitative answer to this question.
01:20Gauss's Law: Cylindrical Symmetry
A charge distribution has cylindrical symmetry if the charge density depends only upon the distance from the axis of the cylinder and does not vary along the axis or with the direction about the axis. In other words, if a system varies if it is rotated around the axis or shifted along the axis, it does not have cylindrical symmetry. In real systems, we do not have infinite cylinders; however, if the cylindrical object is considerably longer than the radius from it that we are interested in,...
01:27Gauss's Law: Planar Symmetry
A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...
01:22Electric Field of a Non Uniformly Charged Sphere
Gauss's law states that the electric flux through any closed surface equals the net charge enclosed within the surface. This law is beneficial for determining the expressions for the electric field for a particular charge distribution if the electric flux is known.
Consider a non-uniformly charged sphere, for which the density of charge depends only on the distance from a point in space and not on the direction. Such a sphere has a spherically symmetrical charge distribution. Here, the electric...
