Reflection peaks variations in multiwall carbon nanotube photonic crystal array

In this paper we analyze the effects of material characteristics (metallic behavior) and the periodicity of dielectric function, on the reflection peaks in a defected two-dimensional multiwall carbon nanotube (MWCNT) photonic crystal, for photon frequencies up to 10 THz. The simulation results show that, the second peak amplitude depends on both material and periodicity changes of the structure, whereas the previous report shows the mentioned dependence only on the material characteristics of structure. It should be noted that, the first and third (Bragg) peaks are dependent only on the material characteristics and the dielectric periodicity, respectively.
