In a recent work we found equivalence between the Time Reversal techniques and the use of Meta-materials in order to achieve the overcoming of the diffraction limit. Now we present the vector generalization of a formalism developed in a former study of Discrete Acoustic Time Reversal. The ulterior purpose is to apply it to electromagnetic waves, not only as an alternative to the use of left-hand materials...
The main purpose of this paper is to compare the numerical simulation of the electromagnetic scattering by a sea surface using a MoM approach and Nodal Discontinuous Galerkin Methods (NDGM).
The Electromagnetic susceptibility (EMS) of cathode ray tube (CRT) display for computer was investigated preliminarily using the test method of bulk current injection (BCI). During the test, CW signals as electromagnetic interference (EMI) signals with different amplitude at a certain frequency were injected into the RGB, horizontal synchronization (HS) and vertical synchronization (VS) signal line...
High-power electromagnetic (HPEM) technology, and the associated effects it can have on modern electronics, is of interest for a variety of non-lethal applications, such as ending dangerous car pursuits and access denial to suspect vehicles. In this paper, we present concepts for using HPEM pulses as a means to remotely stop the engines of cars, describe potential technologies and systems, discuss...
A spatially discretised Reduced Maxwell Bloch model is investigated, which models nonlinear optical propagation through a thin slab of resonant atomic material placed in a recirculating cavity. The model may be used to determine the stationary states of the cavity field, which may then be subjected to stability analysis. The analysis identifies the structure of the canonical integrable discrete model...
During ICEAA 2009, the authors explored the use of hybrid functional models to find failure modes of simple infrastructure models. Pulsed excitation was shown to effective in causing failures in simple oscillators and related simple models, using the energy of the circuit to bring about the failure. A simple SCADA system was used as a practical example of these failure models in infrastructure systems...
This paper examines the applications of statistical physics-stochastic processes, ergodic principles, the use of nonlinear dynamic state equations and chaos, and the Wiener-Khintchine theorem to better explain how Intentional ElectroMagnetic Interference (IEMI) disrupts the performance of feedback and hybrid electronic systems such as control systems, power electronics and SCADAs. The origin of spurious...
Numerical modeling and experiment have the same importance in revealing the unusual properties of electromagnetic metamaterials. On one hand, the numerical modeling can confirm the experiments on metamaterials; on the other hand, it can explore the properties of metamaterials in extreme conditions which cannot be performed experimentally. In this paper, we investigate the numerical modeling of metamaterials...
This paper provides a quasi-three dimensional version of Multi-Level Green's Function Interpolation Method for multilayered problems. In this method the cross level interfaction phase is used to enhance the interpolation efficiency for the multilayered problems with vias and patches. The numerical analysis shows the efficiency of this method.
