“…Considering that RT accuracy for PG modeling in cellular systems for personal communications may commonly correspond to an average RMSE of several dBs, results are here quite in agreement. According to this outcome, surface wave propagation, which has been sometimes claimed as a major propagation mechanism [13,16] does not seem so significant, at least in the considered situations. In fact, it would be accounted for by the FDTD simulation only and therefore would result in a much poorer comparison between the models.…”

“…Therefore, wireless solutions represent today a valid NoC breakthrough to overcome these problems [2,8], especially for long-haul ranges within the chip. According to the existing literature, WiNoC have been mainly investigated at frequency up to hundreds of GHz [12][13][14][15][16].…”

“…According to the chip layered representation, the electromagnetic waves springing out from the on-chip transmitting antenna are expected to bounce onto the interfaces between the layers, thus triggering multipath effects [8,10,14,16,18]. Assuming the antennas buried in a SiO 2 layer limited by two different, unbounded media on the lower and on the upper side [10,18], multipath is fundamentally generated by the multiple reflections between the interfaces ( Figure 5) and can be evaluated by means of the Ray Tracing (RT) approach discussed in [10].…”

Networks-on-chip are being regarded as a promising solution to meet the on-going requirement for higher and higher computation capacity. In view of future kilo-cores architectures, electrical wired connections are likely to become inefficient and alternative technologies are being widely investigated. Wireless communications on chip may be therefore leveraged to overcome the bottleneck of physical interconnections. This work deals with wireless networks-on-chip at optical frequencies, which can simplify the network layout and reduce the communication latency, easing the antenna on-chip integration process at the same time. On the other end, optical wireless communication on-chip can be limited by the heavy propagation losses and the possible cross-link interference. Assessment of the optical wireless network in terms of bit error probability and maximum communication range is here investigated through a multi-level approach. Manifold aspects, concurring to the final system performance, are simultaneously taken into account, like the antenna radiation properties, the data-rate of the core-to core communication, the geometrical and electromagnetic layout of the chip and the noise and interference level. Simulations results suggest that communication up to some hundreds of μm can be pursued provided that the antenna design and/or the target data-rate are carefully tailored to the actual layout of the chip.

“…The solution offers a practical method for analyzing the system using a novel 3D bathtub curve [8]. The on-chip wireless channel and the effect of antenna positioning and directionality on channel characteristics are described in recent research studies [9]. Analysis of the intra-chip environment reveals that it differs greatly from free space and creates smallscale fading effects from various propagation paths from both chip layers and chip edges.…”

A communication channel can be wire-line or wireless. A channel can be used for unicast, multicast or broadcast systems. Wireless communication refers to the electromagnetic transfer of data between two or more points. Communication over radio waves requires an antenna [1−3]. An interconnect connects two electronic devices or networks. Some of the nonwired technologies are RF wireless interconnects, optical interconnects, 3D chips, Alternating Current (AC) coupling, etc. Generally, interconnects are low frequency metal wired connections. An unlicensed spectrum in the range of 60 GHz frequency has gained much more attention in the last few years due to increased demand for very high-speed multimedia wireless short-range communications [5−8].

“…Related to this, it has been demonstrated that the path loss exponent in the optimized cases is between 1 and 1.4, which confirms the waveguiding effect of the whole flip-chip package. Finally, it is worth noting that other aspects such the antenna orientation or placement also have an impact [77] in ways compatible to standard packaging.…”

The miniaturization of transceivers and antennas is enabling the development of Wireless Networks-on-Chip (WNoC), in which chip-scale communication is utilized to increase the computing performance of multi-core/multi-chip architectures. Although the potential benefits of the WNoC paradigm have been studied in depth, its practicality remains unclear due to the lack of a proper characterization of the wireless channel at the chip scale and across the spectrum, among others. In this paper, the state of the art in wave propagation and channel modeling for chip-scale communication is surveyed. First, the peculiarities of WNoC, including the design drivers, architecture, environment, and on-chip electromagnetics are reviewed. After a brief description of the different methods to characterize wave propagation at chipscales, a comprehensive discussion covering the different works at millimeter-wave (mmWave), Terahertz (THz) and optical frequencies is provided. Finally, the major challenges in the characterization of the WNoC channel and potential solutions to address them are discussed, providing a roadmap for the foundations of practical WNoCs.
