Abstract
An MRTD/FDTD hybrid method, according to the shifted interpolation property of Daubechies' scaling function, is employed to analyze scattering of objects above the ground, and the wave on connecting boundary is realized through three-wave technique. The far-fields are computed using reciprocity theorem instead of the complicated Sommerfeld theory, and results are in good agreement with BOR-MoM and FDTD.
