An accurate and efficient physical-optics (PO) near-field integral representation is proposed and introduced into shooting and bouncing ray (SBR) to evaluate the electric and magnetic near-fields scattered from electrically large complex objects illuminated by dipole sources. The PO near-field integral expressions can be reduced to closed-form expressions by applying locally expanded phase approximations and surface partitioning. By introducing the proposed PO near-field integral expressions, SBR can be used to solve near-field scattering problems from electrically large complex objects. Simple and complex numerical examples are presented to demonstrate the efficiency and accuracy of the proposed method.
