Classification of materials for conducting spheroids based on the first order polarization tensor

Abstract: Abstract. Polarization tensor is an old terminology in mathematics and physics with many recent industrial applications including medical imaging, nondestructive testing and metal detection. In these applications, it is theoretically formulated based on the mathematical modelling either in electrics, electromagnetics or both. Generally, polarization tensor represents the perturbation in the electric or electromagnetic fields due to the presence of conducting objects and hence, it also desribes the objects. Und… Show more

“…A range of mathematical formulations have been proposed and used to calculate magnetic polarization tensor for the purpose of metal detection. Khairuddin et al proved the first order polarization tensor of the spheroids and ellipsoids can be used to classify different conductivities of spheroid/ellipsoid samples [21][22]. Khairuddin et al using the hp-FEM method to calculate the polarization tensor of the sample.…”

“…Given the conductivity and geometry of the object, by solving system of integral equation, the associated GPT in the matrix form or in some literatures known as PT for object with specific conductivity can be determined. In other words, given GPT due to the presence of a known or unknown object, the geometry and conductivity of the related object can be described or predicted (15)(16)(17).…”
