Plane Electromagnetic Waves I01:30

Plane Electromagnetic Waves I

5.4K
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...

Gauss's Law: Cylindrical Symmetry01:20

Gauss's Law: Cylindrical Symmetry

10.1K
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,...

Gauss's Law: Planar Symmetry

10.2K
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...

Gauss's Law: Spherical Symmetry01:26

Gauss's Law: Spherical Symmetry

10.0K
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...

Potential Due to a Polarized Object01:29

Potential Due to a Polarized Object

913
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Symmetry in Maxwell's Equations01:28

Symmetry in Maxwell's Equations

4.5K
Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

    Area of Science:

    • Optics
    • Electromagnetism
    • Materials Science

    Background:

    • Previous work established a 'paraxial' (small-angle) ray optics cloaking formalism.

    • Phase matching calculations across the visible spectrum.

    Main Results:

    • The study successfully extends the cloaking formalism to the full-field of light.
    • An isotropic plate with tailored refractive index and dispersion can achieve broadband phase matching in the visible spectrum.
    • Omnidirectionality is identified as the primary trade-off for achieving ideal broadband cloaking.

    Conclusions:

    • The findings support fundamental limits on achieving both broadband and omnidirectional cloaking simultaneously.
    • The research provides insights into the conditions under which anisotropic materials might be necessary for advanced cloaking applications.
    • This work advances the understanding of broadband field cloaking and its practical limitations.
