摘要：

This paper focuses on broadband electromagnetic (EM) modeling of composite materials. A homogenization method is carried out by combining finite element calculations with a numerical inversion technique: first, the transmission and reflection coefficients of the composite plate are computed over a large frequency band (up to 50 GHz) using a 3-D finite-element method. Then an inversion technique is applied in order to extract EM properties. This approach extends the application domain of classical homogenization methods by enabling the modeling of different types of composites.
