The Efficient Method for Calculating the Physical Optics Scattered Fields from the Concave Surfaces
In this work, the numerical steepest descent path (NSDP) method is proposed to compute the highly oscillatory physical optics (PO) scattered fields from the concave surfaces, including both the monostatic and the bistatic cases. Quadratic variations are adopted to approximate the integrands of the P...
