We investigate the clustering and phase separation of a model of ultrasoft, oppositely charged macroions by a combination of Monte Carlo and Molecular Dynamics simulations. Static and dynamic diagnostics, including the dielectric permittivity and the electric conductivity of the model, show that ion pairing induces a sharp conductor-insulator transition at low temperatures and densities, which ...

The usual setting of an eddy current problem distinguishes between a conduct7 ing region and an air region (non-conducting) surrounding the conductor. For the numerical 8 approximation of this heterogeneous problem it is very natural to use iterative substructur9 ing methods based on transmission conditions at the interface. We analyze the convergence 10 of the Dirichlet-Neumann iterative metho...

We analyze the problem of directed quantum transport induced by external exponentially correlated telegraphic noise. In addition to quantum nature of the heat bath, nonlinearity of the periodic system potential brings in quantum contribution. We observe that quantization, in general, enhances classical current at low temperature, while the differences become insignificant at higher temperature....

It is a denture type micro electric field loading device design. The device is a removable partial denture, and there are a power supply and the electrode plate in the denture. The electrode plate embedded in the denture base, electrode embedded in the buccal and lingual base, between the base and the artificial teeth is the power supply, the power supply and both sides electrodes connected by ...

In this paper, the electromagnetic field of a horizontal electric dipole buried in a four-layered region is treated in detail. The region of interest consists of a perfect conductor, coated with the twolayered dielectrics under the air. Because of existing multi-reflections, the final representations of the six field components are much more complex. It is noted that the trapped surface wave an...

In this work, approximate formulas are presented for computing the magnetic field intensity near electric power transmission lines. Original expressions are given for single circuit lines of any type of arrangement and double circuit lines in both super-bundle and low-reactance conductor phasing. These expressions can be used for assessing directly the Right-of-Way width of power lines related ...

In this work, we explore the existence of spoof surface plasmons (SSPs) supported by deep-subwavelength high-contrast gratings (HCGs) on a perfect electric conductor plane. The dispersion relation of the HCGs-based SSPs is derived analyt- ically by combining multimode network theory with rigorous mode matching method, which has nearly the same form with and can be degenerated into that of the S...

9 www.alliedjournals.com  Abstract— Power quality is a very important issue. Non-linear loads and semi-conductor devices connected to AC electric mains generate unwanted signals (harmonics) in the dynamics of current which are responsible for additional power losses in heat loss and the risk of equipment damage or malfunctioning. In the simulink model of shunt active filter fuzzy logic control...

Abstract—The transverse electric (TE) field patterns and characteristics are considered for a cylinder with N infinite axial slots of arbitrary opening size and position. The cylinder is a thin circular conductor and covered by an eccentric material. Radiations are determined by applying the boundary conditions to the cylindrical wave functions of the fields. The addition theorem of Bessel func...

We show that the cubic nonlinear response of a polycrystalline quasi-one-dimensional conductor, such as a conducting polymer, can be expressed exactly in terms of the single-crystal cubic susceptibility and the electric fields in the analogous linear polymer. We also propose a simple nonlinear decoupling approximation which allows the polycrystalline nonlinear susceptibility to be simply estima...
