Graphs

Simple polar graph of the scattering pattern. Light is incident from the left on a sphere located at the center of the polar plot. Since this is a linear plot, you cannot see much unless the anisotropy is moderate.


This is like the polar graph above, except that the radial distance is plotted on a log scale. This is not quite as simple as it looks, since numbers that are smaller than 0.001 get no respect. In fact, they all just get mapped to the origin. So far, they have not complained. The nice thing about this graph is that the shape of smaller side lobes can be seen more easily.
