The authors computer simulations show that plasmon modes excited in an array of field-effect transistors with two-dimensional electron channel strongly couple to terahertz radiation due to the synchronization of plasma oscillations in different unit cells of the array. It is shown that in such a device the higher-order plasmon modes are excited much more effectively than in a large area two-dimensional electron channel coupled to terahertz radiation by a slit-grating gate. Effective excitation of the higher-order plasmon modes makes it possible to design terahertz plasmonic devices with operating frequencies up to 15 THz or even higher.
