“…One such technology is represented by reconfigurable intelligent surfaces (RISs) [4], [5], which can offer artificial LoS paths in NLoS scenarios. The performance improvement obtained in vehicular communication scenarios thanks to RISs was demonstrated by NTT DOCOMO in Japan back in 2018 [6]. One of the most promising enabling technologies for RIS implementation are metasurfaces, that feature subwavelength apertures, and can thus precisely control the impinging electromagnetic waves to realize multiple array functionalities, including steering and diffusion [7].…”

Future cooperative autonomous vehicles will be able to organize into flexible platoons to improve both the efficiency and the safety of driving. However, platooning requires dependable coordination through the periodic wireless exchange of control messages. Therefore, challenging propagation scenarios as found, e.g., in dense urban areas, may hinder coordination and lead to undesirable vehicle behavior. While reconfigurable intelligent surfaces (RISs) have been advocated as a solution to improper coverage issues, no system-level simulation exists that accounts for realistic road mobility and communication aspects. To this end, we present one such simulator built on top of the OMNeT++-based PLEXE and Veins frameworks. Specifically, our contribution is a simulator that takes into account vehicle mobility, physical layer propagation, RIS coding, and networking protocols. To test our simulator, we implement an RIS-assisted autonomous platoon merging maneuver taking place at an intersection where the absence of any RIS would limit successful communications to an area dangerously close to the intersection itself. Our results validate the simulator as a feasible tool for system-level RIS-assisted cooperative autonomous vehicle maneuvering, and ultimately show the benefit of RIS as roadside infrastructure for wireless coverage extension.

Recently, realization of 5G communication systems attract much attention, and high functionality and miniaturizations of semi-conductor devices and electronic devices are required. For these purposes, the polyimides applied as interlayer dielectrics of these devices are expected to show high resolution and reliability in thick films. In this paper, we worked on developing high resolution and low stress negative tone photo-definable polyimide. By combining with high light transmittance polyimide and the UV cure system that suppress active species, we successfully obtained the fine patterns with high resolution even at 40 μm thickness. We also employed the thermal cure system with no cure shrinkage, so that the residual stress was still low even at dry conditions. Our developed polyimide also showed a good insulation reliability by biased HAST (High Accelerated Stress Test).
