Tunable properties of one-dimensional photonic crystals that incorporate a defect layer of a magnetized plasma

Abstract

In this paper, we theoretically investigate the transmittance characteristics of one-dimensional defective photonic crystal in microwave radiations based on the fundamentals of the characteristic matrix method. Here, the defect layer is magnetized plasma. The numerical results show the appearance of defect peaks inside the Photonic Band Gap. The external magnetic field has a significant effect on the permittivity of the defect layer. Therefore, the position and intensity of the defect peak are strongly affected by the external magnetic field. Moreover, we have investigated the different parameters on the defect peaks as the plasma density, the thickness of the plasma layer and the angle of incidence. Wherefore, the proposed structure could be the cornerstone for many applications in microwave regions such as narrowband filters.

Biophotonic sensor for the detection of creatinine concentration in blood serum based on 1D photonic crystal

“…1 These structures present a modulation of refractive indices that can control the propagation of electromagnetic waves and is called the photonic band gap (PBG). 2 The PBG consists of a range of frequencies that forbid the propagation of light and are highly sensitive to external conditions, including mechanical stress, 3 temperature, 4,5 electric eld, 6 magnetic eld, 7 chemicals, 8 pressure, 9 and self-organization of multilayered stacks. 10,11 Therefore, PCs are considered the basis for sensing applications, such as a chemical sensors, 12 pressure sensors, 13 and biosensors.…”

A Novel Comb-Like Nonreciprocal Evanescent Wave Filter Based on the 1-D Ternary Magnetized Plasma Photonic Crystals

“…So far, many efforts have been carried out for studying the transmission properties of the EMWs of the 1-D PPCs consisting of plasma and lossless dielectric [24]- [27]; however, only few studies are available on the nonreciprocal evanescent waves within the magnetized plasma. Here, the transfer matrix method (TMM) [28], [29] and dispersion equations [18] of TM polarization are devoted to analyzing the transmission of the evanescent waves propagating in the 1-D TMPPCs from opposite directions. Thus, some unusual properties of the resonant peaks can be obtained and controlled by adjusting the total number of the periods, the plasma frequency, the plasma cyclotron frequency, the filling factor of the plasma, and the incident angle.…”

“…This remarkable property of tuning the defect mode inside the PBG of defective PCs has inspired various research groups worldwide in their attempts to develop high-performance biosensors. [15][16][17][18][19][20] These biosensors are remarkably attractive to the biomedical and biochemical elds due to their tremendous sensing and detecting capabilities. [21][22][23][24] PCbased biosensors have been widely designed and fabricated for the detection of temperature, hydrostatic pressure, acoustic waves, and magnetic elds.…”
