“…In recent times, a rapid growing interest has been given to quasi-periodic PCs due to their amusing properties over the conventional PCs [13,23,41,42]. One of the most important technological features in simulating one dimensional photonic quasi-periodic crystals is that they are much closer to reality than ordered periodic PCs [41]. Another attractive property is that the PBGs in quasi-periodic PCs could be designed to enlarge band gaps width of light in any frequency range.…”

In this communication, the transmittance characteristics of one dimensional quasi-periodic photonic crystals (PCs) is investigated. The proposed structure consists basically of plasma and nanocomposite layers arranged in accordance to the Fibonacci sequence. The effect of volume density of the plasma and the volume fraction of the nanocomposite material on the properties of the photonic band gaps are studied in detail. The effect of layers thicknesses and the sequence number are also taken into account. We believe that such structures can be potentially beneficial in many novel future applications such as multichannel and pass band filters and optical switches. Additionally, such PCs can be used to design tunable optical devises through controlling the plasma and nanoparticle densities.

“…It has been also shown that such band gaps are insensitive to changes in both polarization of electromagnetic waves and angle of incidence [43,44]. Possibility of having multiple forbidden gaps within the spectrum is potentially leading to important applications [41,44].…”

Enlarged band gap in photonic heterostructure (PC1/PC2) composed of metamaterials and magnetic materials is studied using simple transfer matrix method. As we know that the meta-materials have the unusual electromagnetic properties having negative refractive index. The negative index material is affected with their optical parameters like refractive index, permittivity, permeability and thickness of the materials. The PC1 and PC2 are two photonic crystals containing NIM with different thickness ratio. When these two PCs are combined and make a heterostructure of PC1/PC2 of different thicknesses ratio, then the band gap of such heterostructure is enlarged due to the band gap of PC1 and PC2. Such structure may be used as a broad band filter for TE and TM modes.

“…Dong et al [14] have formed a heterostructure by combining two Fibonacci quasi-periodic structures and a periodic structure and a broad omnidirectional reflection band is obtained. The enlargement of omnidirectional total reflection frequency range of a multilayered dielectric heterostructures is theoretically investigated [15][16][17][18]. Three structures of Na3AlF6/Ge multilayer have been studied [15].…”
