Summary
We developed new broadband electromagnetic Gaussian Schell-model sources with consistent polarization across frequencies. These sources generate beams with linearly polarized light whose polarization angle changes during propagation, offering novel insights into partially coherent light behavior.

Background:
- Understanding the behavior of partially coherent light sources is crucial in various optical applications.
- Gaussian Schell-model sources are widely studied for their well-defined coherence and intensity profiles.
- The interplay between spectral properties and polarization in broadband sources remains an active area of research.
Purpose of the Study:
- To introduce a novel class of broadband electromagnetic Gaussian Schell-model sources.
- To investigate the spectral and polarization characteristics of these sources in the far-zone.
- To explore the propagation dynamics of the polarized component of the generated beams.
Main Methods:
- Theoretical formulation of broadband electromagnetic Gaussian Schell-model sources.
- Analysis of the spectral coherence and polarization properties.
- Mathematical modeling of beam propagation and polarization angle evolution.
Main Results:

01:27Gauss's Law: Planar Symmetry
9.0K
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...

01:26Gauss's Law: Spherical Symmetry
8.7K
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...

01:07Gauss's Law
8.9K
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
8.9K
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,...

01:30Plane Electromagnetic Waves I
4.6K
The existence of combined electric and magnetic fields that propagate through space as electromagnetic (EM) waves is the most significant prediction of Maxwell's equations. As Maxwell's equations hold in free space, the predicted electromagnetic waves do not require a medium for their propagation. An EM wave comprises an electric field, defined as the force per charge on a stationary charge, and a magnetic field, which is the force per charge on a moving charge.
The EM field is assumed to be a...

01:08IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
1.5K
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...
