“…       (10) In ( 8)- (10), 𝜈 is the effective collision rate and ɛ ∞ is the background permittivity. We have determined the permittivity tensor assuming a specific value of the collision rate (ν).…”

“…Graphene is one of the interesting two-dimensional materials which offers a number of fundamentally fascinating features. These properties make graphene a good candidate for designing of novel photonic and electronic devices such as waveguides [1][2][3][4][5][6][7][8][9][10][11][12][13], circulator [14,15], coupler [16], resonator [17], and filter [18]. Graphene plasmonics is a new research area emerged in recent years, which has been developed based on the optical conductivity of graphene that can be varied by either electrostatic or magnetostatic gating.…”

Highly Confined Mid-infrared Plasmonics in Graphene-plasma Cylindrical Structures

“…Based on this tunable parameter, many innovative devices have been designed and fabricated in plasmonics such as sensors [5,6], couplers [7][8][9], filters [10][11][12], resonators [13][14][15], Radar Cross-Section (RCS) reduction-based devices [16][17][18] and circulators [19][20][21][22]. Among these devices, graphene-based waveguides play a remarkable role in graphene plasmonics, which are divided into various platforms such as planar [23][24][25][26][27][28][29][30][31][32][33][34][35], cylindrical [36][37][38][39][40], and elliptical structures [41][42][43][44]. It should be noted that graphene plasmonics is mostly used in the mid-infrared region whereas metal-based plasmonics is a promising candidate in near-infrared frequencies for various applications [45][46][47][48][49].…”

Tunable Plasmonic Modes in Graphene-loaded Plasma Media

“…Based on the propagating properties of Surface Plasmon Polaritons (SPPs) on graphene, various plasmonic components have been designed and investigated in the THz frequencies such as sensors [5,6], couplers [7][8][9], filters [10][11][12], resonators [13][14][15], and circulators [16][17][18][19]. Among these devices, graphene-based waveguides play a remarkable role in graphene plasmonics, which are divided into various platforms such as planar [20][21][22][23][24][25][26][27][28], cylindrical [29][30][31][32][33], and elliptical structures [34][35][36][37]. It should be noted that graphene plasmonics is mostly used in the mid-infrared region whereas metal-based plasmonics is a promising candidate in near-infrared frequencies for various applications [38][39][40][41][42].…”
