Multi-Objective Design Optimization of Conductive Shield for Eddy Current Systems Based on Multiple Continuum Sensitivity

This paper proposes a design method to solve the multi-objective optimization problems of conductive shields in eddy current systems. The conductive shield is designed to protect the outer area of the system from the magnetic field while maintaining the system performance. The design sensitivities for the conductor shape corresponding to each objective function are calculated through the continuum method. The multi-objective design velocity is obtained from the multiple continuum sensitivity. The shape evolution is expressed using the level set method. The proposed method is verified by applying it to the design of conductive shields in a magnetic induction tomography system.
