Total current (/) on the cylinder of figure 1, for a=b, 6 (original) (raw)

TABLE 1 Total current (/) on the cylinder of Figure 1, for a=b, 6 =0, E,;=1V/m, and f = 1 GHz, obtained by the finite-difference method (FD) and the boundary-element method (BE). Given also are the step size (s), the number of steps along a(n,), and the number of pulses per conductor side (n) for the boundary-element method. The phase of the electric field is zero at the conductor axis

Finite-difference solution of scattering by a rectangular cylinder (TM) using exact mesh termination

Abstract:Finite Difference Techniques for solution of "steady state'' frequency domain Helmboltz equation is quite simple and straightforward. Howeuer, for open regions, the finite difference mesh needs to be terminated so that the proper boundary conditions are imposed for the sohtion. A hybrid method is described in this paper which guarantees that the boundaly conditions generated for the termination of the open region mesh is exact. The conditions are generated from the Green's functions. The technique is applied to the solution of electromagnetic scattering by conducting cylinders (TM case).
