Implementing the EIT complete electrode model through Robin boundary conditions
Bing-Zhou Chen, Amelia Deakin, Andy Adler +2
Objective. Medical electrical impedance tomography systems prescribe electrode currents. Accurate voltages, even on passive electrodes, require the complete electrode model (CEM),…
Characterising buried objects in metal detection
P. D. Ledger, W. R. B. Lionheart
Current mathematical models for identifying highly conducting buried objects in metal detection assume that the soil is non-conducting and has the same permeability as free space.…
How far are two symmetric matrices from commuting? With an application to object characterisation and identification in metal detection
P. D. Ledger, W. R. B. Lionheart, J. Elgy
Examining the extent to which measurements of rotation matrices are close to each other is challenging due measurement noise. To overcome this, data is typically smoothed and Riema…
Efficient Computation of Magnetic Polarizability Tensor Spectral Signatures for Object Characterisation in Metal Detection
James Elgy, Paul D. Ledger
Purpose: Magnetic polarizability tensors (MPTs) provide an economical characterisation of conducting magnetic metallic objects and their spectral signature can aid in the solution…
Characterising small objects in the regime between the eddy current model and wave propagation
P. D. Ledger, W. R. B. Lionheart
Being able to characterise objects at low frequencies, but above the limiting frequency of the eddy current approximation of the Maxwell system, is important for improving current…
Properties of Generalised Magnetic Polarizability Tensors
P. D. Ledger, W. R. B. Lionheart
We present new alternative complete asymptotic expansions for the time harmonic low--frequency magnetic field perturbation caused by the presence of a conducting permeable object a…
