Abstract
A uniform geometrical theory of diffraction (UTD) enhanced physical optics and time domain integral equation (PO-TDIE) hybrid algorithm is proposed. UTD is applied to calculate the edge effect and to compensate the calculation error made by the PO current approximation. This method can improve the accuracy while maintaining the computational complexity, compared to PO-TDIE. Numerical result illustrates the validity and efficiency of the proposed method.
