Maxwell's Equation Of Electromagnetism01:29

Maxwell's Equation Of Electromagnetism

3.7K
James Clerk Maxwell (1831–1879) was one of the major contributors to physics in the nineteenth century. Although he died young, he made major contributions to the development of the kinetic theory of gases, to the understanding of color vision, and to understanding the nature of Saturn's rings. He is probably best known for having combined existing knowledge on the laws of electricity and magnetism with his insights into a complete overarching electromagnetic theory, which is...

Electromagnetic Waves

James Clerk Maxwell formulated a single theory combining all the electric and magnetic effects scientists knew during that time, calling the phenomena his theory predicted “Electromagnetic waves”. He brought together all the work that had been done by brilliant physicists such as Oersted, Coulomb, Gauss, and Faraday and added his own insights to develop the overarching theory of electromagnetism. Maxwell’s equations, combined with the Lorentz force law, encompass all the laws...

Magnetic Fields

6.7K
A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.
A magnetic field is defined by the force that a charged particle experiences...

Symmetry in Maxwell's Equations

3.9K
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...

Electromagnetic Fields

2.5K
Electric fields generated by static charges, often referred to as electrostatic fields, are characteristically different from electric fields created by time-varying magnetic fields. While the former is a conservative field, implying that no net work is done on a test charge if it goes around in a complete loop in the field, the latter is, by definition, not a conservative field; net work is done, and it is proportional to the rate of change of magnetic flux.
However, the observation of...

Potential Due to a Magnetized Object01:24

Potential Due to a Magnetized Object

659
Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.
The vector...

Area of Science:

  • Electromagnetism
  • Nanophotonics
  • Surface Science

Background:

  • Macroscopic electromagnetic boundary conditions are foundational in photonics but fail at the nanoscale.
  • Classical models neglect intrinsic electronic length scales, causing discrepancies with experiments below 20 nm.
  • Existing approaches are limited, lacking a unified framework for multiscale nanoscale electromagnetism.

Purpose of the Study:

  • Introduce and demonstrate a general, unified framework for nanoscale electromagnetism.
  • Incorporate electronic length scales into classical descriptions using surface-response functions.
  • Provide a computationally feasible approach for multiscale electromagnetic problems.

Main Methods:

  • Introduced a framework utilizing Feibelman d parameters to reintroduce electronic length scales.
  • Developed an experimental procedure to measure complex dispersive surface-response functions.
  • Employed quasi-normal-mode perturbation theory and observed nonclassical effects.

Main Results:

  • Observed nonclassical spectral shifts exceeding 30% in film-coupled nanoresonators.
  • Demonstrated the breakdown of Kreibig-like broadening in multiscale architectures.
  • Validated the framework's applicability to systems with feature sizes comparable to electronic and wavelength scales.

Conclusions:

  • The introduced framework successfully bridges classical and quantum descriptions of electromagnetism at the nanoscale.
  • Feibelman d parameters provide a means to accurately model phenomena across relevant length scales (above ~1 nm).
  • This work offers a general approach for understanding and modeling nanoscale electromagnetic phenomena.
