“…Sci. 2019, 9, 5488 8 of 34 coupled plasmonic antennas may become a drastic solution for a successful coupling without losses [40,41], enabling a hybrid optical wireless approach in the NoC design. The efficient coupling between plasmonic antennas and SOI waveguides is a non-trivial issue, as an on-chip, point-to-point connection normally requires matched directive nanoantennas.…”

Wireless data traffic has experienced an unprecedented boost in past years, and according to data traffic forecasts, within a decade, it is expected to compete sufficiently with wired broadband infrastructure. Therefore, the use of even higher carrier frequency bands in the THz range, via adoption of new technologies to equip future THz band wireless communication systems at the nanoscale is required, in order to accommodate a variety of applications, that would satisfy the ever increasing user demands of higher data rates. Certain wireless applications such as 5G and beyond communications, network on chip system architectures, and nanosensor networks, will no longer satisfy speed and latency demands with existing technologies and system architectures. Apart from conventional CMOS technology, and the already tested, still promising though, photonic technology, other technologies and materials such as plasmonics with graphene respectively, may offer a viable infrastructure solution on existing THz technology challenges. This survey paper is a thorough investigation on the current and beyond state of the art plasmonic system implementation for THz communications, by providing in-depth reference material, highlighting the fundamental aspects of plasmonic technology roles in future THz band wireless communication and THz wireless applications, that will define future demands coping with users' needs. Appl. Sci. 2019, 9, 5488 2 of 34 communications, researchers have been focused on taking advantage of higher regions in the radio spectrum, pointing to the THz band communication and infrastructure, as a promising solution to equip 5G plus networks, thus enabling efficient operation of bandwidth hungry applications, that are not feasible at the moment with current infrastructure.Wireless NoC (WiNoC) [5] with its inherent broadcast capability, appears as a promising approach to overcome all abovementioned bottlenecks of ancestor technologies. Ultra small miniature sizes of plasmon based antennas and other nanolink components as well, with considerably much less wiring, are the desired features of this technology, in order to enable the integration of one or multiple antennas per core, paving the way for dense, scalable NoC schemes, as required by future applications. Graphene based WiNoCs (GWiNoCs) is probably the most updated promising approach for THz nanoscale wireless communications, and it is therefore considered to be the basis for implementing future on chip network architectures. Alternatively, hybrid optical wireless schemes, may be also proved to be a promising NoC solution [6], by combining the best assets of these two worlds: low loss dielectric waveguide media, and miniature sized plasmonic material oscillating at THz rates.Last, wireless nanosensor networks (WNSNs) is another established THz nanoscale application, with basic similarities as in WiNoCs, such as core to core or to memory communication, but also with other unique characteristic types of communication, mainly between nanosensors and nanomachin...

“…From our analysis of the nanoantenna with an infinite substrate, we see that most of the radiation is directed into the substrate. Therefore, only a fraction of the total power can be extracted from the plane parallel to the nanoantenna, as required in the case of a nano-link [1,2]. In this section we investigate the effects of a reflective ground plane beneath the substrate.…”

“…Ramaccia et al first studied horn nanoantennas with a gradual exponentially tapered structure where Metal-Insulator-Metal waveguides with cylindrical metallic pillars were incorporated [12]. A similar structure was adopted by Yang et al [2] where they designed a broadband and highly directive E-plane horn [16] nanoantenna with straight flares fully incorporated in a homogeneous medium. In [1], Yang et al extended the same horn antenna concept, where a plasmonic channel waveguide, along with the flared section, was carved in a silver film.…”

“…As a result, only a fraction of the total power can be coupled or extracted from the end-fire direction, as the antenna radiation will be directed elsewhere. Thus, there is a need to engineer the radiation of these nanoantennas, so that they can radiate in any given direction, for applications in wireless nano-links [1][2][3][4][5][6], and laser detection and ranging [17]. Previously, plasmonic substrates (i.e.…”

In this paper, we study a plasmonic horn nanoantenna on a metal-backed substrate. The horn nanoantenna structure consists of a two-wire transmission line (TWTL) flared at the end. We analyze the effect of the substrate thickness on the nanoantenna's radiation pattern, and demonstrate beam steering in a broad range of elevation angles. Furthermore, we analyze the effect of the ground plane on the impedance matching between the antenna and the TWTL, and observe that the ground plane increases the back reflection into the waveguide. To reduce the reflection, we develop a transmission line model to design an impedance matching section which leads to 99.75% power transmission to the nanoantenna.

“…Many results for nonlinear PT -symmetric models, where the gain-loss balance is combined with the usual equilibrium between diffraction and nonlinear selfinteraction, were summarized in reviews [44] and [45]. The PT -symmetry has also been studied extensively in multidimensional systems [45,46,47,48,49,50]. An issue of obvious interest is to produce multi-dimensional integrable models featuring the PT symmetry, which is a motivation for the consideration of eqs.…”

Recently, an integrable system of coupled (2 + 1)-dimensional nonlinear Schrödinger (NLS) equations was introduced by Fokas (eq. (18) in Nonlinearity 29, 319324 (2016)). Following this pattern, two integrable equations [eqs.(2) and (3)] with specific parity-time symmetry are introduced here, under different reduction conditions. For eq. (2), two kinds of periodic solutions are obtained analytically by means of the Hirota's bilinear method. In the long-wave limit, the two periodic solutions go over into rogue waves (RWs) and semi-rational solutions, respectively. The RWs have a line shape, while the semi-rational states represent RWs built on top of the background of periodic line waves. Similarly, semi-rational solutions consisting of a line RW and line breather are derived. For eq. (3), three kinds of analytical solutions,viz., breathers, lumps and semi-rational solutions, representing lumps, periodic line waves and breathers are obtained, using the Hirota method. Their dynamics are analyzed and demonstrated by means of threedimensional plots. It is also worthy to note that eq. (2) can reduce to a (1 + 1)-dimensional "reverse-space" nonlocal NLS equation by means of a certain transformation, Lastly, main differences between solutions of eqs. (2) and (3) are summarized.
