Dear MPB-users, I have a question concerning the built-in commands (compute-group-velocities) and (compute-group-velocity-component direction). For photonic crystals and photonic crystal line-defect structures (run-te display-group-velocities) works fine, but for the two lower level functions listed above I couldn't have found a way to make them run. Regarding the link below, can anyone send me a sample code that pass them into a function? http://blog.gmane.org/gmane.comp.science.photonic-bands/month=20041201 In a triangular lattice line defect PhCW, if I want to calculate the “X” component (in cartesian) of group velocity, can I write the direction of group-velocity-component (vector3 0.866 0.866 0) ? (cartesian->reciprocal (vector3 1 0 0)) ==> (0.866 0.866 0) Thank you very much.
