Electric Field of Parallel Conducting Plates01:16

Electric Field of Parallel Conducting Plates

1.5K
Gauss' law relates the electric flux through a closed surface to the net charge enclosed by that surface. Gauss's law can be applied to find the electric field and the charge enclosed in a region depending on its charge distribution.
Consider a cross-section of a thin, infinite conducting plate having a positive charge. For such a large thin plate, as the thickness of the plate tends to zero, the positive charges lie on the plate's two large faces. Without an external electric field, the...

Symmetry in Maxwell's Equations

4.0K
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...

Potential Due to a Polarized Object

645
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,...

Electric Field of a Charged Disk01:23

Electric Field of a Charged Disk

2.9K
The simplest case of a surface charge distribution is the uniformly charged disk. Calculating its electric field also helps us calculate the electric field of a large plane of charge.
The system's symmetry is in the cylindrical directions across the plane of the charge. As a result, the electric fields created by various surface charge elements nullify each other in the direction parallel to the surface. Thereby, the resulting electric field is perpendicular to the plane. Since the disk is...

Magnetic Field due to Moving Charges01:23

Magnetic Field due to Moving Charges

11.1K
A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

Magnetic Vector Potential01:15

Magnetic Vector Potential

1.4K
In electrostatics, the electric field can be written as the negative gradient of the potential. In magnetostatics, the zero divergence of the magnetic field ensures that the magnetic field can be expressed as the curl of a vector potential. This potential is known as the magnetic vector potential.
Consider an ideal solenoid with n turns per unit length and radius R. If I is the current through the solenoid, the magnetic field inside the solenoid is expressed as the product of vacuum...

Area of Science:

  • Nanophotonics
  • Plasmonics
  • Quantum Optics

Background:

  • Chiral metallic nanostructures, such as plasmonic vortex lenses (PVLs), generate spin-dependent plasmonic vortices (PVs) governed by plasmonic spin-orbit coupling.

  • To theoretically reveal a general spin-to-orbit coupling mechanism.
  • To experimentally demonstrate the existence of multiple PV modes in a single PVL.

Main Methods:

  • Theoretical analysis of spin-to-orbit coupling in chiral nanostructures.
  • Experimental demonstration using fixed circularly polarized vortex beam excitation.

Main Results:

  • Counterintuitively discovered nontrivial deuterogenic PVs in addition to the previously predicted single PV mode.
  • Demonstrated the simultaneous existence of multiple PVs within a single PVL.

  • The findings provide a deeper fundamental understanding of near-field spin-orbit coupling dynamics in nanophotonics.
  • This work paves the way for flexible manipulation of PVs in on-chip optical vortex-based nanotechnologies and quantum optical applications.
