TL;DR: A new research direction of software‐defined metAsurfaces is described, which attempts to push metasurfaces toward unprecedented levels of functionality by harnessing the opportunities offered by their software interface as well as their inter‐ and intranetwork connectivity and establish them in real‐world applications.
Journal ArticleDOI
Graphene-enabled wireless communication for massive multicore architectures
TL;DR: This position paper presents a new research area where massive multicore architectures have wireless communication capabilities at the core level by using graphene-based planar antennas, which can radiate signals at the Terahertz band while utilizing lower chip area than its metallic counterparts.
