Tunnelling is a powerful tool for the determination of one-electron structures of two-dimensional systems. Recently a strong interaction between cyclotron and intersubband tunnelling resonances was observed in the case when one-particle Landau levels of different two-dimensional subbands do not interact. In this connection the long-wave structure of quasi-two-dimensional magnetoplasmons is calculated for the actual system of two quasi-two-dimensional layers divided by a barrier in a perpendicular magnetic field. It is shown that the Coulomb interaction between the intersubband, intrasubband and combined resonance magnetoplasmons is able to lead to strong anticrossing of their terms. Magnetoplasmon-assisted tunnelling processes will reveal themselves as the anticrossing of Landau levels of different two-dimensional subbands. This paper was presented at the 3rd Russian Workshop on Nanophotonics, Nizhnii Novgorod, Russia, 26-29 March 2001.
