In a photonic crystal (PC) array, a line defect (removal of a periodic structure) and position up-chirping (gradually decreasing lattice constant) are familiar terms to introduce light confinement and propagation due to the photonic bandgap (PBG). In this paper, we have proposed a new model for light confinement using a line defect position chirped PC array with metamaterial as a dielectric material. For comparison, we have designed and simulated for both line defect positions chirped and none position chirped PC array using normal material (refractive index +3.927) dielectric material and metamaterial (refractive index −3.927). We have used metamaterial due to the compensation of light dispersion and leakage effect because the negative refractive index makes the wave vector direction precisely opposite to the positive refractive index material. We have implemented the metamaterial positioned chirped PC array with sharp 90° bending and shown the light confinement and propagation for that structure. To support our proposed model, we have calculated the band diagram of both positive refractive index and metamaterial unit cells and verified the quantum well existence in the band diagram of metamaterial unit cell. Based on the quantum well effect, the confinement of light in metamaterial line defect position chirped PC has been explained and presented with proper finite element method (FEM) simulations. From quantum mechanics, we can comprehend that confining wave particles at the atomic level is extremely challenging because of the evanescent nature of the light wave. The novelty of this paper is that we have managed to confine the propagating of light waves by using the quantum well existence in the metamaterial dielectric for a line defect position chirped PC structure, and to the best of our knowledge, we are probably the first to introduce light confinement using a metamaterial chirped PC structure with proper FEM simulation.

“…Also, graphene is a material with interesting electromagnetic properties for terahertz bands [4,5]. Many papers have implemented graphene in antennas as resonators, and substrates [6][7][8][9][10][11][12]. These, allows miniaturized design without losing its radiating characteristics and frequency tuning due chemical potential changes in complex conductivity [13].…”

Antennas with high performance and technological materials are relevant for several application on THz band. In this work, we investigate the cylindrical dielectric resonator antenna (CDRA) with non-resonant microstrip patch (NMP) feed combined with a thin layer of graphene on the top of the Dielectric Resonator (DR) designed for 3.30 THz. The NMP structure provides high order HEM12δ mode with great advantages in gain values and radiation efficiency. The graphene layer associated with the NMP structure provided improvements in gain and return loss, as well as, tuning characteristics by changing the chemical potential. The antenna was simulated in Ansys HFSS, and the results obtained with NMP radius of 12.7 µm are S11=-37.98 and 7.9 dB gain. Besides, the bandwidth increased 6.6% to 20%. These results corroborate the effectiveness and enhancement of the antenna parameters providing a great alternative for Terahertz band applications.

These metamaterials have been considered for their unusual behaviors, such as controlling the current 4 and phase 5 in the microstrip antenna or manipulating the electromagnetic light 6 . Furthermore, Metamaterials can be used for designing various devices such as microwave absorber 7 and metasurface 8 .…”

In this article, an antenna with the combination of the microstrip slot and Yagi antenna is presented for wideband WLAN (wireless local area network) using CRLH (composite right/left‐handed) as a metamaterial (Left‐hand) element. The T‐shape feed line is investigated as a radiator section and modified for enhancing the bandwidth. The periodic elements are utilized as a novel type of the director to improve the bandwidth to more than 35% and increase the gain of the antenna to more than 80% where the three CRLH elements array are employed as the director of the Yagi antenna. The proposed antenna covers the 2.2 to 8 GHz (113% bandwidth) with a return loss of less than −6 dB (VSWR less than 3), which makes it suitable for wireless applications for covering different bands including WLAN, LTE (Long Term Evolution), and WiMAX with 47% miniaturization. The final antenna is simulated with CST microwave studio by the time‐domain method of FIT (Finite integration technique). The total size of the antenna is 60 mm × 40 mm × 1.6 mm, which is printed on an FR‐4 substrate, and the experimental results confirm the simulations.
