Abstract :
An efficient method to evaluate the surface fields excited on an electrically large dielectric coated circular cylinder is presented. The efficiency of the method results from the φ-propagating representation of the Green´s function as well as its efficient numerical evaluation along a steepest descent path. Numerical results are presented for current elements mounted on a dielectric coated cylinder and compared with reference solutions
