Abstract :
In this paper, we demonstrate a possibility of increasing computational efficiency of the MoM-FDTD hybrid method by employing spatial interpolation combined with adaptive sampling in calculating the electric and magnetic field components and equivalent sources on the Huygens´ surfaces. Along with the direct spatial interpolation of the electromagnetic field components on the Huygens´ surface we also examined the improved interpolation and adaptive sampling scheme employing the non-uniform sampling intervals and well known spatial dependence of the field to smooth it before interpolation.
