Macroscopic electric characterization of bundles of conductors

The author explains how the ohmic behaviour of a bundle of conductors can be characterized by a complex resistivity. He provides an analytical expression, explicit and simple, of that resistivity and shows how to optimize an HF transformer, using that formula together with a previously published expression of the macroscopic magnetic permeability. >

Algebraic decomposition of the electromagnetic constitutive tensor: A Step toward pre-metric based gravitation?

It is known that the electromagnetic constitutive tensor can be algebraically decomposed in three parts: the so-called principal part, the axion part and the skewon part (see gr-qc/0506042). The aim of this paper is to provide a deeper decomposition of the principal part. Comment: 12 pages, PDF only

Rigorous definition of the transformation ratio in the presence of magnetic saturation and leakages

This paper proposes a new method for modelling multi-winding devices with non-linear magnetic core. This method is founded on rigorous theoretical bases. It is successfully applied to the study of a voltage transformer for 245 kV network.
