Table 2 shows the comparisons of the CPU time and memory used by the conventional FDTD with CFLN = 1, conventional ADI FDTD with CFLN = 1 and 10, proposed leapfrog ADI-FDTD with
Method CFLN Number of CPU Memory steps Time (s) (MB) leapfrog 1 2000 25 3.7 ADI-FDTD 10 200 2.6 3.7 ADI-FDTD 10 200 3.3 4.1 FDTD 1 2000 9.4 3.7
When CFLN = 5 and CPW = 30, the processes of controlling parameters of the efficient 4-stages SS-FDTD_1 method and the efficient 4-stages SS-FDTD_2 method are shown in Table 2.
When CPW = 20 and CFLN = 1, 5, the information on the controlling parameters of the efficient 4-stages SS-FDTD_1 method and the efficient 4-stages SS-FDTD_2 method are shown in Table 3.
Figures 4 and 5 show the time domain response of the voltage across lumped networks obtained by the proposed LN-ADI-FDTD formulations and the conventional LN-FDTD formulations for different CFLN values.
The computed results computed by the LN-ADI-FDTD method as CFLN varying from 0.75 to 4.5 are shown in Fig.
Becoming there the object of a bitter and sustained campaign calling for his indictment and trial, he was arrested in August 1943 on the orders of the CFLN. He was finally put on trial before a military court on 4 March 1944, charged with collaboration, with placing the French police in the service of the Germans, and with establishing the sections speciales.
Figure 1 shows that the dispersion (normalized phase velocity) error of the proposed method increases with increasing CFLN. The sub-time-step in Figure 1 is taken up to 4, just to see the dispersion trend.
It is observed that at CFLN = 10 (time step 10 times larger), the FADIFDTD and Yee's excplicit FDTD methods are in excellent agreement with each other.
Time variations of [E.sub.x] in the input and output planes are calculated with TRC-LOD-FDTD method for CFLN = 10, and depicted in the Figure 4.
Figure 1 shows the [E.sub.z]-field at the observation point for the ADI-FDTD and four-step ADI-FDTD methods with CFLN = 6.
When CFLN = 5 and CPW = 20, the processes of controlling parameters of the E-SSCN6-FDTD method are shown as in Table 2.
