Surface equivalent modeling of layered composite material

This work focuses on multilayer composite material modeling. A surface model of two reinforced woven fiberglass composites (polyamide- and epoxy-based) is built using a multilayer effective media theory and a layered anisotropic material model embedded in a Method of Moment solver. Experimental characterizations of the electromagnetic complex relative permittivity of these materials are done using an impedance cell method for low frequencies and a resonant cavity method for frequencies above 1GHz. The results obtained for these two materials are compared to simulation results obtained by modeling the measurement setups and the materials under test.
