Materials thermal properties investigation by inverse modeling technique

Résumé

New materials play very important role in industrial, scientific and medical sectors. Accurate knowledge of their mechanical, electrical and thermal properties is a prerequisite for the development of novel and original applications. Many techniques were developed for the determination of these parameters, often under conditions of use of these materials [1-2]. In applications involving the use of microwave energy, the strong interaction between electromagnetic waves and materials provided a new means of investigation in addition to conventional techniques. The use of multiphysics simulation software based on the numerical resolution of coupled partial differential equations offers the possibility of simulating the dynamic system more or less close to real conditions [3-4]. Combining well-controlled and mastered experimental means, simulation tools allow us to go back to the physical properties of the system studied, including the thermal properties of the materials under test. In this article we propose to characterize the thermal properties of new materials by an inverse modeling technique. It consists in minimizing an objective function built from experimental measurements and multi-physical simulations and then in extracting the desired thermal parameters.
