Abstract
A Domain Decomposition Finite Difference Time Domain (DD-FDTD) method is proposed to solve the problem of electromagnetic scattering from very large rough surfaces. The coupling to the Huygens' surface above a specific subdomain from induced currents on the rough surface in adjacent subdomains is determined by using the reciprocity theorem. The normalized radar cross sections (NRCS's) obtained with the DD-FDTD method match well with those using the conventional FDTD method.
