Distributed active radiation for THz signal generation

In this paper, we introduce the distributed-active-radiator (DAR) structures which consolidate the signal generation, multiplication, filtering, and radiation in a single active electromagnetically coupled structure. As examples of distributed active radiators, we demonstrate 2x1 and 2x2 arrays of DAR structures radiating at 300GHz, which achieve three orders of magnitude higher total radiated power than previously reported.
