The calculation of the dynamical response is performed in the framework of the random-phase approximation using the tight-binding approximation for the electronic ground state. The dependences of the dispersion relations of the magnetoplasmons on the propagation direction, magnetic field and period of the lateral multiwire superlattice are investigated in detail. It is shown that the magnetoplasmon spectrum shows fine-structure effects. Special attention is directed to the strong-confinement case, where the size-quantization effects in each wire are most important and electron tunnelling between the wires is weak. 收起
