It is essential to alter effective electromagnetic parameters of a material to enhance its response. In the present work, we propose a novel Left Hand Metamaterial (LHM) structure comprising double turn spiral resonator (DTSR) and capacitance loaded strips (CLS). This structure is numerically explored to examine the resonance and effective material parameters i.e. permeability and permittivity....

A familiar analogy to the propagation of the electric wave in a nerve lies in the burning of a cigarette. This analogy, which has persisted through several editions of popular textbooks of physiology, has never been elaborated beyond a cursory mention. In this article, the analogy is reinvoked and refined to explain the cable properties of nerve, saltatory conduction, and some other factors aff...

cases of CHB. In these cases, a common finding, in addition to involvement of the aortic valve, was extension of the infection to adjacent structures resulting in cardioaortic fistulae. CHB likely resulted from extension of infection to the major conduction tissues. Five of the six patients with CHB died suddenly while in the hospital. One patient was treated with electric pacing while the infe...

The control of the magnetism of ultra-thin ferromagnetic layers using an electric field, rather than a current, has many potential technologically important applications. It is usually insisted that such control occurs via an electric field induced surface charge doping that modifies the magnetic anisotropy. However, it remains the case that a number of key experiments cannot be understood with...

Ion transport through nanopores drilled in thin membranes is central to numerous applications, including biosensing and ion selective membranes. This paper reports experiments, numerical calculations, and theoretical predictions demonstrating an unexpectedly large ionic conduction in solid-state nanopores, taking its origin in anomalous entrance effects. In contrast to naive expectations based ...

We derive an effective Hamiltonian that describes the dynamics of electrons in the conduction band of monolayer transition metal dichalcogenides (TMDC) in the presence of perpendicular electric and magnetic fields. We discuss in detail both the intrinsic and the Bychkov-Rashba spin-orbit coupling induced by an external electric field. We point out interesting differences in the spin-split condu...

Electric shock is the only effective therapy against ventricular fibrillation. However, shocks are also known to cause electroporation of cell membranes. We sought to determine the impact of electroporation on ventricular conduction and defibrillation. We optically mapped electrical activity in coronary-perfused rabbit hearts during electric shocks (50 to 500 V). Electroporation was evident fro...

Spectral line profiles, broadened mostly by Stark effects from electric fields produced by charge particles, and dielectronic satellite line intensities have recently been used for determining electron densities in the dense region of lasercreated plasmas [1-3]. We present here a direct comparison of electron density measurements in the conduction region of laser created plasmas on a plane targ...

First measurements of temperature fluctuations in a region of high velocity shear show that absolute and normalized fluctuation levels are reduced across the shear layer, a result that is consistent with weak parallel electron thermal conduction in the electron temperature dynamics. The concomitant reduction of temperature, density, and electric field fluctuations reduces the anomalous conducte...

The electric vehicle (Ve) is struck by their low autonomy. To remedy this problem, we opted for the choice of a converter structure in electromagnetic switch, since it has no power dissipation in switching and conduction. The development of a control law of motorization continues saving energy and its implementation under the environment of MATLAB / SIMULINK, led to the scientific results of hi...
