AB - Lossy dielectric and magnetic obstacles are typically
present in many high-frequency scattering applications. In this
paper, we study this problem using the Equivalence Principle
and the Method of Moments (MoM). When the structure is
complex and high accuracy is required, the number of unknowns
in the numerical solution naturally grows. Therefore, we propose
the use of wavelet-like bases to improve the numerical efficiency
and memory requirements. For verification purposes, the results
provided by the new technique are successfully compared with
those obtained with the conventional MoM approach. The new
technique has been applied to characterize the scattering behavior
of large square and elliptical obstacles, as well as multilayer
structures, which are composed of lossy homogeneous media and
conductors.
