A self-similar fractal model is presented for obtaining the dipole moments of chains of equally spaced dielectric spheres immersed in a uniform electric field. The sphere pair is selected as the generator. The dipole moments are calculated iteratively in terms of those of this generator. At each...

A notch of finite width and infinite uniform length in a perfectly conducting ground plane covered by a dielectric slab is considered. Excitation of the notch is by a surface wave with a transverse magnetic (TM) mode of propagation in the grounded dielectric slab. An integral equation is derive...
8(a)), resulting in a uniform grain distribution. In a certain frequency range, the mg-doped CCTO films have higher dielectric constants and good thermal stability. More critically, the doping of Mg reduces the grain boundary conductivity, enhances the grain boundary insulation and finally leads ...
R I d I z=0 2 Dielectric dipole radiation A sphere of homogeneous linear dielectric material with permittivity is placed in an otherwise uniform electric field E0, as shown in Fig. (2). Find the electric field everywhere. Now the external field is made to slowly oscillate at frequency ω,...
DIELECTROPHORESIS is the unidirectional motion of neutral, polarizable material which results from the presence of a non-uniform d.c. or a.c. electric field. It is one of a variety of aligning, rotating and translating effects produced by the action of electrical fields on particles suspended in...
where we have used that the radial field components decay as \(1/r^2\) and hence do not contribute to the flux. Theory of optical tweezers of a dielectric sphere embedded in a chiral medium Here we combine the previous results in order to develop a generalization of the Mie-Debye theory...
possessing a higher permittivity than the surrounding liquid, undergo an electrical force directed toward the region of maximum stress. When using electrodes with a uniform field, particle movement is believed to initiate because of irregularities on the electrode surfaces, generating localized field gradi...
Electronic polarisation: in atoms, positive ions are surrounded by electron clouds. Since the electrons are very light, they respond rapidly to the action of an applied electric field.Figure 7.6shows a schematic of an atom being polarised due to the action of the fieldE0. ...
Moreover, the achieved polarization is not complete and uniform, since it is disturbed by the thermally induced motion. Suggesting that the electric field is applied for a sufficient period time, the dielectric will reach an equilibrium state where polarization attains its maximum value corresponding ...
