| Abstract: | This paper has theoretically studied the characteristic frequencies
of band structures in two-dimensional metallic-dielectric photonic
crystals. It is demonstrated that a large filling fraction benefits
the existence of absolute photonic band gap, while a smaller filling
fraction benefits an absolute negative refraction band. In addition,
it also finds that the relation between the cut-off frequency of
E-polarized wave and the filling fraction exceeding 10{\%} is content
with a linear increasing function, whose coefficients are exponential
to the normalized lattice constant. These investigations have
significant implications for tuning the operational frequencies to
desired applications and manufacturing photonic crystals. |
