In this paper, some numerical simulations by a new high-speed low order (3)-finite difference time domain (HSLO (3)-FDTD) method with direct-domain (DD) and temporary-domain (TD) approaches are conducted to simulate one dimensional free space wave propagation represented by a Gaussian pulse. The simulation is conducted on 2 meter of solution domain truncated by a simple absorbing boundary condition. The efficiency of the new schemes are analyzed and compared with the standard finite difference time domain (FDTD) method in terms of processing time, amplitude and global error. The new schemes (HSLO (3)-FDTD by both approaches) solve the problem faster and produce similar result to the output simulated by the standard FDTD.
