Electrical Conductivity Identification of Waste Particles Using Eddy-Current

Abstract

In this article, we propose a new approach based on the non-destructive method by eddy currents (EC) to identify the conductivity of millimeter materials. Our work is based on the simulation of different wastes which are chosen in rectangular form. The calculation of the normalized impedance of the sensor on the particles of the waste allowed us to successfully identify the conductivity of the materials. This impedance change with the conductivity of each material can be used in the characterization of the waste materials. An extrapolation based on the linear programming method (LPM) us to estimate the frequency and next to identify the conductivity of new materials introduced in the test. The obtained results of this characterization by LPM are found to be consistent and satisfactory.
