dielectric medium उदाहरण वाक्य

The stress energy tensor for an electromagnetic field in a dielectric medium is less well understood and is the subject of the unresolved Abraham Minkowski controversy.
In physics, "'dielectric relaxation "'refers to the relaxation response of a dielectric medium to an external, oscillating electric field.
For a waveguide entirely filled with a homogeneous dielectric medium, similar expressions apply, but with the wave impedance of the medium replacing " Z " 0.
Where ? is the permittivity of the dielectric medium, " A " is the cross sectional area of the electrodes and " d " is the distance between them.
For a waveguide or transmission line containing more than one type of dielectric medium ( such as microstrip ), the wave impedance will in general vary over the cross-section of the line.

The latter paper rigorously shows that spectroscopic microscopy permits determining the nature of deeply subdiffraction three-dimensional refractive-index fluctuations of a linear, label-free dielectric medium in the far zone.
where k is the wavenumber of the electric field, R is the radius of the particle, is the relative permittivity of the dielectric medium and is the relative permittivity of the nanoparticle defined by
The idea was conceived by James Clerk Maxwell in his 1861 paper " On Physical Lines of Force, Part III " in connection with the displacement of electric particles in a dielectric medium.
To solve for the electromagnetic modes, which are decided by the wave vector of the incident plane wave, in periodic dielectric medium, the Maxwell's equations ( in partial differential form ) as well as the boundary conditions are expanded by the Floquet functions and turned into infinitely large algebraic equations.
The geometric dependence of the fields of a Gaussian beam are governed by the light's wavelength ? ( " in " the dielectric medium, if not free space ) and the following "'beam parameters "', all of which are connected as detailed in the following sections.
