 +In this example we plot eigenmode corresponding to band 7 at wavevector 0.4. This is waveguide mode (it also can be seen from results for bandstructure). We choose gnuplot parameter 'cmax=4' for better color resolution (for other eigenmodes optimal value of cmax could be different). We plot real part of eigenmode <tex>{\rm Re}({\bf E})</tex>. Electric field in time is a combination of real and imaginary parts: <tex>{\rm Re}({\bf E}\exp{(i\omega t)})</tex>.
