摘要：

A new fourth-order finite-difference time-domain (FDTD) scheme has been developed that exhibits extremely low-phase errors at low-grid resolutions compared to the conventional FDTD scheme. Moreover, this new scheme is capable of combining with the standard Yee scheme to produce a stable hybrid algorithm, The problem of wave propagation through a building is simulated using this new hybrid algorithm to demonstrate the large savings in computing resources it could afford, With this new developement, the FDTD method can now be used to successfully model structures that are thousands of wavelengths large, using the present day computer technology.
