TLDR
In this article, the characteristics of 2D dielectric rod array with square cross-section elements arranged in square lattice are analyzed in detail, and empirical expressions for both the relative bandwidth of frequency band gap and midgap frequency with respect to the average permittivity, under the optimal filling fraction of dielectrics/air in crosssection for wider bandwidth, are formulated by means of data fit.Abstract:
�H by extending Bloch theorem to the vector field Maxwell equations, the characteristics of 2-D dielectric rod array with square cross-section elements arranged in square lattice is analyzed in detail. From the numerical results, empirical expressions for both the relative bandwidth of frequency band gap and the midgap frequency with respect to the average permittivity, under the optimal filling fraction of dielectric/air in cross-section for wider bandwidth, are formulated by means of data fit.read more
