# Determination of the magnetic permeability, electrical conductivity, and thickness of ferrite metallic plates using a multi-frequency electromagnetic sensing system

## TL;DR

This paper presents an inverse multi-frequency electromagnetic sensing method to accurately determine the magnetic permeability, electrical conductivity, and thickness of ferrite metallic plates, enhancing non-destructive evaluation techniques.

## Contribution

The paper introduces a novel inverse approach using multi-frequency electromagnetic measurements to simultaneously reconstruct multiple material properties of ferrite plates.

## Key findings

- Successfully reconstructed permeability, conductivity, and thickness from spectroscopic data.
- Demonstrated improved accuracy over traditional single-frequency methods.
- Applicable to non-destructive testing of ferrite materials.

## Abstract

In this paper, an inverse method was developed which can, in principle, reconstruct arbitrary permeability, conductivity, thickness, and lift-off with a multi-frequency electromagnetic sensor from inductance spectroscopic measurements. The system fives the error of "Bad character(s) in field Abstract" for no reason. Please refer to manuscript for the full abstract.
