Abstract:
A method for generating property estimates of one or more preselected properties of a material comprising:providing an electromagnetic structure capable of imposing a magnetic field in the material when driven by an electric signal and sensing an electromagnetic response, an analyzer for applying an electric signal to the electromagnetic structure and a property estimator for translating sensed responses into estimates for one or more preselected properties to the material; defining a dynamic range for the preselected properties of the material; selecting an electromagnetic winding geometry and configuration for the electromagnetic structure; generating property estimation grids for the preselected material properties and analyzing the grids and curves to define a measurement strategy; optimizing operating point properties and winding geometry and configuration; with the electromagnetic structure, sensing electromagnetic responses at each operating point; and converting electromagnetic responses into estimates of the preselected material properties.
