“…The transmission spectrum of the MPC structure was calculated based on the theoretical model described on the previous section. The calculations are carried out in the region where ε ′ A and µ ′ A are simultaneously negative, where a new gap, called the zero-n gap [36], will appear [36][37][38][39]. Layer B is assumed to be the vacuum layer with ε B = µ B = 1.…”

Transmission properties of one-dimensional lossy photonic crystals composed of negative and positive refractive index layers with one lossless defect layer at the center of the crystal are investigated by the characteristic matrix method. The results show that as the refractive index and thickness of the defect layer increase the frequency of the defect mode decreases. In addition, it is shown that the frequency of the defect mode is sensitive to the incidence angle, polarization and physical properties of the defect layer but it is insensitive to the small lattice loss factor. The height of the defect mode is very sensitive to the loss factor, incidence angle, polarization, refractive index and thickness of the defect layer. It was also shown that the height and the width of the defect mode are affected by the number of the lattice period and the loss factor.The results can lead to designing new types of narrow filter structures and other optical devices. * email address: alireza.aghajamali@fsriau.ac.ir † email address: barati@susc.ac.ir

“…In recent years, the details of properties and characteristics of the zeron gap of 1D MetaPC structure consisting of DNG and double-positive (DPS) materials have been investigated. Some examples of these investigated properties include the bandwidth, the depth, and the central frequency of the gap [13][14][15][16][17][18][19]. In 2007, Depine et al [20] and Singh et al [21], who published their reports approximately at the same time, demonstrated that in 1D MetaPC, in addition to the zeron and conventional Bragg gaps, two new gaps appear in the transmission spectra for both TE and TM polarized waves.…”

The effects of electric and magnetic loss factors on zero- and zero- gaps in a one-dimensional lossy photonic crystal composed of double-negative and double-positive materials are theoretically investigated by employing the characteristic matrix method. This study contradicts the previous reports as it indicates that by applying the inevitable factors of electric and magnetic losses to the double-negative material, the zero- and zero- gaps appear simultaneously in the transmission spectrum, being independent of the incidence angle and polarizations. Moreover, the results show that these gaps appear not only for an oblique incidence but also in the case of normal incidence, and their appearance at the normal incidence is directly related to the magnetic and electric loss factors. Besides, the results indicate that as the loss factors and angle of incidence increase, the width of both gaps also increases.

“…In the first part, we investigated the properties of the defect mode in the present structure with DPS defect layer, and used equations (3) and (4) [13] in the range of frequency where the zero-n gap appears [11,[13][14][15]. At the second part, additionally, properties of the defect mode of present MetaPC with DNG defect layer are investigated.…”

“…While periodicity plays an important role in the conventional Bragg gap as it is formed by the destructive interferences of electromagnetic waves in the PC, the zero-n gap, to the contrary, is independent of periodicity [12]. In recent years, researchers have examined the properties and characteristics of the zero-n gap of 1D MetaPC structure consisting of DNG and double-positive (DPS) materials as they have published papers on the bandwidth, the depth, and the central frequency of the gap [13][14][15][16][17][18].…”
