The frequency-dependent nonlinear dielectric increment of dipolar fluids in nonpolar fluids is often measured by using a stationary relaxation method in which two electric fields are used: The static direct current (dc) field of high strength causing the dielectric nonlinearity, and the probing alternating current (ac) field of low strength and high frequency. When a nonlinear composite is subj...

We design a high dynamic range electric field sensor based on domain inverted electro-optic (E-O) polymer Y-fed directional coupler for electromagnetic wave detection. This electrode-less, all optical, wideband electrical field sensor is fabricated using standard processing for E-O polymer photonic devices. Experimental results demonstrate effective detection of electric field from 16.7V/m to 7...

This paper deals with the numerical computation of electromagnetic (EM) energy absorption by biological tissues. It is indeed one of the important challenges for the computational EM community to estimate rate of EM energy absorption by human tissues to asses the potential health hazard quantitatively. This is usually quantified in terms of SAR, which is the normalized rate of energy absorbed b...

The origin of thermal ion outflows exceeding 1 km/s in the high-latitude F-region has been a subject of considerable debate. For cases with strong convection electric fields, the “evaporation” of the ions due to frictional heating below 400–500 km has been shown to provide some satisfactory answers. By contrast, in the more frequent subclass of outflow events observed over auroral arcs, called ...

Electromagnons, which are coupled polar and magnetic excitations in magnetoelectric materials, of large interest for electronic computing technological devices. Using molecular dynamics simulations based on an ab initio effective Hamiltonian, we predict that the frequency several electromagnons can be tuned by application electric fields model multiferroic ${\mathrm{BiFeO}}_{3}$, with this eith...

The variations of the electrical conductivity with temperature and electric field of the ternary alloy of gallium, aluminium and arsenic (Al0.75Ga0.25As) with atomic compositions of 99/1 and 98/2 have been investigated. The electrical conductivity of the alloy increases with temperature according to the relation, ? = ?0 exp (??/kT). The activation energy calculated from this empirical relation ...
