A simple moment solution is given for the problem of electromagnetic scattering from multiple conducting and lossy dielectric cylinders of arbitrary cross-section. The conductors may be of the form of strips and the dielectrics may be in the form of shells. The system is assumed to be excited by a plane wave polarised transverse magnetic to the axis of the cylinders. The equivalence principle is used to replace the conductors by surface electric currents and the dielectrics by equivalent surface electric and magnetic currents. Three coupled integral equations are obtained by using the condition on the tangential component of the electric field produced by these surface currents. The method of moment is used to solve the integral equations. A point matching technique is used with pulse expansion functions. Sample numerical results such as the induced currents on the conductors, the total near field, the scattered far field and the radar cross-section are presented. The agreement with available published data is excellent.
