Dear Prof.Steven and mpb-users, In the “Photonic Crystals: Molding the Flow of Light” book, at page 80, the dispersion graph of a square array of dielectric columns in air relating to TM bands is given(Figure 13 of chapter 5). The 4. TM band twists upwards from M through Gamma k-point. However, in the calculated dispersion graph with mpb, at k-point (0.21645 0.21645 0) this band twists downward at the intersection point with the 5. TM band. Why is that artifact arise from? Thank you. Regards. Fulya Bagcı _______________________________________________ mpb-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/mpb-discuss
