half sine wave.The width of the incident wave is taken to be CY units and the square has sides of length CY units.Since the equations are linear,we can take E,= 1 unit.The incident wave will have only an E,component and an H,component.We choose
4 finite difference scheme over the whole x-y plane is impractical; we therefore have to limit the extent of our calculation region.We assume thaatt time t = 0,the left traveling plane wave is “near” the obstacle.For a restricted period of time,we can therefore replace the original problems by the equivalent problem shoxn in
Fig.2.
The input data are takfernom the incident wave
From the differential equation satisfied by Ez n-e conclude that the results for the equivalent problem (see
Fig.2) should approximate those of the original problems,provided
0 5 nAr 5 64Ar,
because the artificial boundary conditions will not affect our solution for this period of time.
For n>64,however,only on certain points n-ill the results of the equivalent problems approximate those of the original problems.Numerical results are presented for the ThI waves discussed above.To gain some idea of the accuracy of the finite difference equation,we have used the system
(14a)-(14c) with the initial E,being a half sine wave for the case of no obstacle.We note that the outer boundary conditions will not affect this incident wave as there is no H,component in the incident wave.
Ninety-five time cycles were run with the finite difference system (14a)-(14c),and the machine output is shown in Fig.3.The oscillation and the widening of the initial pulse is due to the imperfection of the finite difference system.Figure 4 shows the value of E,of the TA.1 wave as a
