I am trying to plot a graph with contourplot and I only get a graph that is completely gray with two white lines in it. Conversely, when I plot it using 3dplot i see that it really should have two plateaus (well, with the default scale) that exponentially decrease on either sides of the plateaus. In this case R is 2, e1 is -50+.6i, e is 2/e1, and k0=2pi/500*10-9. Does anyone have any suggestions?
