Abstract :
This paper presents a new set of formulas to compute the field distribution near an electrically large conductor modeled by non-uniform rational B-spline (NURBS) surfaces using physical optics (PO) method. Results obtained by these formulas and by traditional PO method using triangle modeling technique agree well, which show the accuracy and efficiency of the formulations.
