Geometrically Balanced Metal Detector Based on Optimized Frequencies and Spatial Phase Profile Responses to Discriminate Different Metal Rods Features

Yves Perriard, Christian Köchli, Chafic Abu Antoun

Inductive detection with double-balanced coils and a spatial phase profile were used to identify copper and steel rods in a composite target. The electromagnetic detection system was designed and validated using a dipole model. Simulations and experiments ...

Validity Tests of Superposition Principle Based on Forward Model for Electromagnetic Induction Scattering

Yves Perriard, Christian Köchli, Chafic Abu Antoun

Low-frequency electromagnetic scattering from conductive and permeable bodies is the main principle of detection devices. To be able to classify the objects in the base material, a fast forward model based on the dipolar approximation was developed and ver ...

Frequency Analysis of Finite Steel Cylinders and their Comparison to Complex Cylinder-like Targets using an Electromagnetic Induction Sensor

Yves Perriard, Christian Köchli, Chafic Abu Antoun

This paper shows that the standard industrial targets that need to be detected using an electromagnetic induction sensor cannot be represented by their exact size definition in international standards. Reinforcing steel with defined 16mm diameter according ...
