The numerical analysis of a gradiometric coil arrangement has been performed and the response of a metallic material in the vicinity of the coil system has been examined. The system has been excited by a bandwidth limited step function, thus the step response of the different target materials can be measured on the gradiometer. The 3D numerical model has been prepared in the CST EM Studio environment and has been solved by the finite element method. The simulations have been executed for different target materials, i.e. aluminum, steel, stainless steel and in order to unveil the specific contribution of the magnetic permeability and the electric conductivity to the step response for four fictive materials. The results show that the step response is an appropriate parameter to distinguish between the target materials and to provide information about the sensor to target distance.
