Johnson<br/>Previous methods for determining photonic quasicrystal (PQC) spectra have relied on the use of large supercells to compute the eigenfrequencies and/or local density of states. In this paper, we present a method by which the energy spectrum and the eigenstates of a PQC can be obtained by solving Maxw...<br/>[Phys. Rev. B 77, 104201] Published Fri Mar 07, 2008 Alejandro W.
