Electromagnetic scattering from coated nihility circular cylinders, illuminated by E-polarized plane wave, is investigated using an iterative procedure. Cylinders are infinite in length. The boundary conditions areapplied on the surface of each cylinder in an iterative procedure in order to solve for the field expansioncoefficients. The effect of different types of the coating layers including double positive (DPS) and doublenegative (DNG) on the alteration of the forward and backward scattering has been observed. Specially,the effect of dispersive and dissipative DNG coating layer has been focused. Numerical verifications arepresented to prove the validity of this formulation by comparison with the published literature
