Magnetostatic Boundary Conditions01:28

Magnetostatic Boundary Conditions

1.8K
An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...

Interference and Diffraction02:18

Interference and Diffraction

53.9K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Boundary Conditions for Current Density

1.4K
Current density becomes discontinuous across an interface of materials with different electrical conductivities. The normal component of the current density is continuous across the boundary.

Radiation Pressure: Problem Solving01:09

Radiation Pressure: Problem Solving

956
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Standing Waves in a Cavity01:28

Standing Waves in a Cavity

1.6K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Dynamic Equilibrium02:20

Dynamic Equilibrium

66.4K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Summary
This summary is machine-generated.

Transition radiation from periodically deformed dielectric interfaces generates multiple peaks instead of one. The number and location of these peaks depend on charge incidence angle and interface period.

Area of Science:

  • Physics
  • Electromagnetism
  • Optics

Background:

  • Transition radiation occurs when charged particles cross an interface between two media.
  • Periodic structures can modify electromagnetic wave interactions.

Purpose of the Study:

  • To derive a formula for transition radiation on a periodically deformed dielectric interface.
  • To analyze the spectral-angular distribution of radiated energy for nonstatic interface profiles.

Main Methods:

  • Derivation of a formula for spectral-angular distribution of radiated energy.
  • Numerical analysis for triangular and sinusoidal grating profiles.

Main Results:

  • A formula for transition radiation on periodically deformed interfaces is derived under the assumption of close dielectric permittivities.
  • The study includes cases of propagating surface waves.
  • Numerical examples for triangular and sinusoidal gratings show a set of peaks in backward transition radiation, unlike the single peak for a flat interface.

Conclusions:

  • The number and location of radiation peaks are dependent on the incidence angle of the charge and the interface period.
  • Conditions for the appearance of these multiple peaks are specified.
