【Abstract】 The FDTD method based on the scattering of thin wire was derived in this paper. This method can be used to compute the radiation/scattering of thin wire structure. It is simpler and more efficient than that of the traditional FDTD method. The radiation and scattering of a linear antenna are studied by using the FDTD method and EFIE method. The results, which were validated by EFIF method, proved that the FDTD method based on the scattering of thin wire is very efficient for the solution of thin wire structure.更多还原
