We derive the analytic expressions of the electromagnetic force and torque on a dipolar particle, with arbitrary dielectric permittivity and magnetic permeability. We then develop a general framework, based on the coupled dipole method, for computing the electromagnetic force and torque experienced by an object with arbitrary shape, dielectric permittivity and magnetic permeability.

We consider the diffraction of a plane wave on layer symmetric hyperbolic metamaterial made metal and SiO 2 layers. It is shown that reflection coefficient depends not only angle incidence, but also direction incidence relative to anisotropy axis. In an arbitrary fall, plate asymmetric creates scattered waves both polarizations. Keywords: metamaterial, diffraction, effective permittivity tensor...

The bias-field-dependent dielectricity of ferroelectric thin films is studied by use of a multilayer model capable of modeling saturated and unsaturated hysteresis behavior under arbitrary fields. The simulated minor hysteresis loops at different bias fields are used to calculate the variation of dielectric permittivity with the bias field. The -E loops show asymmetric shifting along the field ...

Marble beams were subjected to gradually increasing three-point bending from low loading levels up to levels that significant damage was observed. After each loading step the permittivity was measured at three characteristic locations: the tensional, middle and compressional zone of each sample. The permittivity measurements were conducted in the frequency range from 1kHz to 1MHz. The permittiv...

SiO2 hollow spheres and low relative permittivity insulation paper handsheets composed of these SiO2 hollow spheres with different weight percentages were successfully prepared. Low-content SiO2 hollow spheres were uniformly dispersed in the insulation paper handsheets. The relative permittivity of the immersed oil Kraft-SiO2 hollow sphere handsheets (K-SiO2) initially decreased and then increa...
