UWB Analysis of EM Fields in Complex Laminates: A Multiresolution Homogenization Approach

In this paper we have presented an MRA homogenization approach for electromagnetic radiation and propagation in the presence of complex laminates. The formulation addresses a general 3D source configuration via plane-wave spectral expansion, yet here we have limited our study to a single plane wave (single spectral parameter $), emphasizing the UWB aspects of the theory. We have demonstrated how the medium homogenization scale (M-HS) should be chosen as to accommodate the wide frequency spectrum of the excitation. In particular we examined two alternative schemes for choosing the M-HS, a dispersive and a non dispersive scheme, and demonstrated how they are used in order to calculate the effective transient response. Finally we have used the effective Wronskian equivalence to calculate the SEM resonances of a randomly laminated complex slab.
