| Abstract(in English) | Although the contrained interpolation profile (CIP) method has a smaller numerical dispersion when compared with the standard Yee's finite difference time domain (FDTD) algorithm, the electric and magnetic field arrangements of CIP method make it difficult to model antennas into the analysis space. A hybridization of CIP method and FDTD method is proposed to solve the problems of large- or long-distance propagation space including antennas in this paper. The boundary conditions between CIP and FDTD method are also considered and validated. The results show that the numerical dispersion of the hybrid CIP-FDTD method is almost same as that of the CIP method, which is superior to that of the FDTD method. |
