Abstract

A GPU-based parallel hybrid method is proposed to accelerate the electromagnetic scattering from electrically large complex structures in high frequency. The MPO and the GRECO hybrid method can simplify the computations of the diffraction fields of the wedges by modifying the surface-normal vector of the target to redefine the surface equivalent currents. By using GPU-based reduction operation, we design a fast parallel summing method for the hybrid integrals over illuminated triangles. The hybrid method is validated by comparing the numerical results with those obtained through the serial computing program on a central processing unit, as well as through FEKO method of moments, which showed good agreement.
