چکیده:

Photonic crystal structures have a certain photonic band gap that prevents propagating of wave (light) in certain frequencies with certainpolarizations or incident angles. The properties of this band gap (attenuation and bandwidth) depend on parameters of the dielectric periodic structure, such as relative permittivity constant ( r ε ), Fill Factor (f), etc, that would be discussed. In this paper, we will consider the properties of a scaled measurement of two-dimensional square lattice of dielectric columns. It has a band gap in microwave frequencies (instead of light wave
frequencies) due to its big scale. Also, we simulate other structures for approaching our desired parameters of band gap and observe effects of changing the parameters of the structure on the properties of the band gap (using S-parameters).
