Surface Wave Attenuation in Multilayer Structures With Lossy Media and Impedance Surfaces

“…The Example #3 is a single layer lossy dielectric slab with air on top. This kind of structure is often analyzed also in other papers [26]- [28] but with comparatively lower loss scenario. This example can be considered as the natural evolution of the previous example, i.e.…”

“…This structure is interesting since it is typically employed in the design of antenna radomes and also for the construction of fiberglass ships [33], [34]. The Example #5 is represented by a resistive coated grounded dielectric substrate, which is typically employed for designing Salisbury absorbers [28], [35], [36]. This structure provides higher attenuation of surface waves than the uncovered lossy dielectric.…”

“…The critical points or the range or initial guess are required to these searching methods for finding the roots of the characteristic equation. Moreover, most of the methods have been developed for single layer low loss structures [25]- [28]. Complex propagation constant of SWMs in general multilayer structures have been computed but with the condition defined as ε << ε [29].…”

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].…”
