Bi-static scattering width control of multiple coated PEC cylinder

In this study, we propose the method that determines the coated parameter values of the cylinder satisfying the desired bistatic scattering width (SW). We consider the infinitely long perfectly electric conductor (PEC) cylinder, which is illuminated by plane wave whose polarization is parallel to cylinder axis. Unknown scattered field coefficients are expressed by using boundary conditions in terms of coating parameters for fixed wavelength and radius of cylinder. Far field SW is obtained using the scattered coefficients and then steepest descent method is used to control the bi-static SW according to each coating complex wave number and thickness. Minimised bi-static SW was compared to those of PEC cylinder and good reduction values were observed over a wide frequency range and angle.
