# Viewing the Results

View and post-process the results in POSTFEKO.

View the computed scattering width as a function of the bistatic observation angle (ϕ) for a cylinder radius of r=0.1 and r=0.6.
1. The scattering width is obtained by using the equation at the top of the example with the values provided to simplify to
(1) $SW=2\pi 500\mid E{\mid }^{2}$ .
2. To use the equation in POSTFEKO, ensure the magnitude of the electric field is displayed.
3. Select the Enable maths check box and enter the following:
2*pi*500*ABS(self)^2
Compare the results with the literature reference (C. A. Balanis, Advanced Engineering Electromagnetics, Wiley, 1989, pp. 607.). The results agree well with the literature reference.
