Abstract
We propose an approach originating from plane wave expansion method
to calculate band structure for two types of honeycomb lattice two-dimensional
plasma photonic crystals. The eigenvalue equations of E-polarization for two
types of structures, which depend on the honeycomb lattice realization(plasma
rods immersed in dielectric background or vice versa), are derived respectively.
A standard linearization technique which solves the general nonlinear eigenvalue
problem has been used to obtain the photonic band structures. The resulting
complex band structure yields, in addition to the dispersion curves, the dissipation
of each type as it propagates through the system. By properly selecting structure
parameters for the two types of plasma photonic crystals, moderate band structures
can be obtained to meet the needs of application. The proposed method can
be used for any infinite periodic lattice and the results may provide theoretical
instructions to design new optoelectronic devices.
