چکیده
|
We investigate theoretically the optical properties of a 2d photonic band-gap crystal (square lattice of circulardielectric rods in air) through the plane-wave expansion method. we calculate the photonic band structure for bothte and tm polarizations for the 2d photonic structure. band gaps exist only for tm polarization (e parallel to therods). also we study the effect of varying the dielectric constant of the rods and the rods radius-to-pitch ratio r/a onthe first gap appeared in the photonic band structure for tm polarization.
