Summary:
Recently, photonic band-gap (PBG) structures are under intense research due to their various applications in optics, microwave, and antenna engineering. Therefore, the accurate modelling of band diagram of frequency-dependent PBG structures is highly needed because the electric properties of all of the materials depend on frequency. In this paper, a new finite-difference frequency-domain (FDFD) algorithm is derived to calculate the propagation modes in frequencydependent PBG structures. For validity of this method, the results are compared with the finitedifference time-domain (FDTD) method.
