In this paper an efficient method is proposed for computing electromagnetic wave propagation over terrain profiles. The paper extends the Tabulated Interaction Method (TIM) [1], applying it to the problem of 2D wave scattering from lossy surfaces using a coupled surface integral equation formulation. The proposed method is compared with the recently proposed Chacracteristic Basis Function Method (CBFM) [2], [3] with which it shares several features. The numerical analysis demonstrates that TIM has a dramatically lower computational complexity and storage than CBFM.
