Magnetoinductive e ects in ferromagnetic conductors can be used for various sensors. Although the principle has been known for a long time, the usefulness of these e ects for practical applications was recognized recently, and intensive investigations began. Magnetoinductive e ects are related to magnetization of a magnetic conductor (wire, strip, thin lm, etc.) by a magnetic eld, which is prod...

Soil ionisation has an important influence on impulse characteristics of grounding conductor. This paper introduced improvements to existing soil model considering the electric field change resistivity, while resistivity is not directly dependent field. The validity improved was verified by surge response vertical conductor in uniform and horizontally stratified soil. Furthermore, experiment ca...

The method of images is most often employed in electrostatic examples with point or line charges in vacuum outside conducting planes, cylinders or spheres [1]. Develop similar prescriptions for the electric scalar potential in examples where the conductor is a linear, isotropic dielectric medium with relative permittivity . Discuss also media with relative permeability μ when a line current or ...

Axial symmetry in x-ray radiation of wire-array z pinches is important for the creation of dynamic hohlraums used to compress inertial-confinement-fusion capsules. We present the first evidence that this symmetry is directly correlated with the magnitude of the negative radial electric field along the wire surface. This field (in turn) is inferred to control the initial energy deposition into t...

A novel MatLab-based diffraction tool for the investigation of scattered fields around a two-dimensional Perfectly Electric Conductor (PEC) wedge is introduced. Analytical (Exact by Integral, as well as some High Frequency Asymptotic (HFA) techniques) and numerical (Finite-Difference Time-Domain (FDTD)) models are included. The FDTD staircase modeling problems are removed by the application of ...

This article shows the interfacial relation in electrodynamics shall be corrected in discrete grid form which can be seen as certain numerical dispersion beyond the usual bulk type. Furthermore we construct a lossy conductor model to illustrate how to simulate more general materials other than traditional PEC or simple dielectrics, by a new conformal FDTD method which main considers the effects...

We study the formation and propagation of a normal zone in Rutherford-type superconducting cables. We use a rectangular conductor model to account for the electric current redistribution process between the multifilamentary strands in the presence of a normal zone. We obtain and integrate numerically the diffusion equations for the temperature and the current density distributions. Our simulati...

Recently developed multiresolution frequency domain (MRFD) technique is applied to two-dimensional electromagnetic scattering problems. Scattered field formulation and perfectly matched layer is implemented into the MRFD formulation. Far field distributions of dielectric and perfectly electric conductor (PEC) bodies are calculated and bistatic echo widths of these structures are presented. Good...

We present the mathematical foundation for a point-source method PSM to solve inverse electromagnetic perfect-conductor obstacle scattering problems. The PSM gives a new and explicit procedure how to compute locally from the far eld pattern E 1 an approximation for the total electric eld E near the unknown obstacle. The PSM then searches for the boundary of the obstacle as a zero-curve of p E w...

This paper investigates the millimeter electromagnetic waves passing through a metal nanogap. Based upon the study of a perfect electrical conductor model, we show that the electric field enhancement inside the gap saturates as the gap size approaches zero, and the ultimate enhancement strength is inversely proportional to the thickness of the metal film. In addition, no significant enhancement...
