Toward practical applications over 100 GHz

Abstract

This paper discusses practical applications of the frequency band starting at 100 GHz—a band that has yet to be fully exploited. It considers the feasibility of future applications driven by the sub-terahertz and terahertz bands, examining this feasibility from two perspectives: (1) market needs and the standards being released to meet these needs mainly in the area of communications applications, and (2) advances in semiconductor technologies and their peripheral technologies. To discuss approaches to implementing these applications, we present two transmission technologies that we are developing.
