The features of the method of moment (MoM) and the finite difference time domain (FDTD) method for numerical analysis of the electromagnetic scattering problem are presented. First, the integral equations for the conducting wire, conducting plane and the dielectric materials are described. Importance to ensure the condition of the continuity of the current of the scatterers is emphasized and numerical examples for a conducting structure involving a junction of wire segment and planar segment is presented. Finally, the advantages and the disadvantages of the FDTD method are discussed.
