Efficient formulation of high-order boundary conditions for the high-frequency modeling of multilayer composite slab

Abstract

Boundary conditions for laminated composite panels reinforced with thin fibers are derived starting from the exact analytical model of an array of parallel conducting wires excited by a plane wave. Once evaluated the impedance sheet condition and the corresponding wave-transmission matrix valid for a single lamina, shielding performances of the whole panel are examined and compared with the results obtained considering each lamina as a homogeneous and anisotropic layer.
