Resistivity Tensor Imaging via Network Discretization of Faraday's Law

Inverse Estimation of the Flow Resistivity Tensor of Open-Cell Foams from Experimental Data and Darcy’s Flow Simulations

The flow resistivity tensor, which is the inverse of the viscous permeability tensor, is one of the most important material properties for the acoustic performance of open cell foams, used in acoustic treatments. Due to the manufacturing processes, these foams are most often geometrically anisotropic. This paper discusses the estimation of the flow resistivity tensor using an improvement of a p...

Chapter 8 Curl-conforming Edge Element Methods 8.1 Maxwell's Equations 8.1.1 Introduction

Electromagnetic phenomena can be described by the electric field E, the electric induction D, the current density J as well as the magnetic field H and the magnetic induction B according to Maxwell's equations given by Faraday's law ∂B ∂t + curl E = 0 in lR 3 , (8.1) where according to the Gauss law div B = 0 in lR 3 , (8.2) and Ampère's law ∂D ∂t − curl H + J = 0 in lR 3 , (8.3) where, again o...

Resistivity Tensor Probability Tomography

The probability tomography approach developed for the scalar resistivity method is here extended to the 2D tensorial apparent resistivity acquisition mode. The rotational invariant derived from the trace of the apparent resistivity tensor is considered, since it gives on the datum plane anomalies confined above the buried objects. Firstly, a departure function is introduced as the difference be...

We show that if we consider the full statement of Faraday's law for a closed physical circuit, the standard Maxwell's equations in the presence of electric and magnetic charges have to include in their integral form a mixed term of the form ρ m v ⊥ e where ρ m is the magnetic charge density and v ⊥ e the perpendicular component of the velocity v e of the electric charge. Maxwell's electrodynami...
