由物理的直观来看,非等向性的光子能隙(anisotropic photonic bandgap)来自于光子晶体晶格中的布里渊区(first Brillouin Zone)的低对称性;而一个完全的光子能隙(complete photonic bandgap),或称为等向性的光子能隙(isotropic photonic bandgap),则可借由...

the first Brillouin zone 第一布里渊区
Phonons have complicated dispersion relations which generally have several acoustic and optical branches, the phonons in acoustic branches called acoustic phonons. The dispersion of acoustic phonons are linear around the center of the first Brillouin zone.
