Band structure and EFCs of the second band of the 2D PhC of hexagonal lattice for TM polarization. Values of frequency are in units of . (a) Surfaces of the second band and light cone. (b) EFCs of the 2nd band. The blue dotted circle is the line of intersection of the second band surface and the light cone.
