Knowledge Bases, Cooperation Networks, and Influential Contributions of Channel Modeling for Terahertz Communications

The terahertz communication in the band 0.1-10 THz is well recognized as one of the supporting paradigms for the next generation of wireless communication. The channel modeling for THz communications has attracted lots of attention in the literature, which produces complex knowledge relationships. Since technical contributions and potential applications have been widely reported in the field, it is necessary to make clear the underlying knowledge development paths and directions. In this work, we use the co-citation analysis and co-occurrence analysis of CiteSpace to recognize the knowledge bases and cooperation networks behind the literature of the channel modeling for THz communications as well as the influential contributions in the field. Technical knowledge bases such as THz channel modeling and ray tracing as well as application knowledge bases such as nano communication and smart rail mobility are detected. Both author and institution cooperation networks worldwide are recognized, and the top 18 institutions and top 11 contributions are also recognized based on the number of citations, which is helpful to establish cooperative relationships in channel modeling for THz communications.
