In this study, electromagnetic scattering from inhomogeneous impedance cylinder of arbitrary shape have been solved by means of transformation of problem into equivalent problem, that is scattering from circle represented by high order inhomogeneous impedance boundary condition (IBC). High order impedance functions are determined by using shape of object and its surface impedance. Then, equivalent problem is solved by means of series expansion method. This transformation makes the problem simple formulation, which can be solved computational effectively. Results and computational times obtained by transform method and those obtained by Method of Moment (MoM) technique are compared. Good agreements are observed in results. It is also observed that transform method needs less computational time than MoM method. (C) 2008 Wiley Periodicals, Inc.
