Analysis of Electromagnetic Propagation from MHz to THz with a Memory-Optimised CPML-FDTD Algorithm

Figure 6

Electric field distribution () for free space for a 2.45 GHz frequency. On the left, the FDTD-CPML case is shown, while on the right, the reference propagation (extended domain). In (a), (b), and (c), we show snapshots at 150,650,700, respectively. We observe an excellent wave absorption without presenting spurious reflected waves. The simulation lasted for 1160 time steps, and the source was turned off at .
