Recent results in the topical and rapidly developing branch of spintronics and magnetoelectronics called magnonics are presented in this paper. The paper describes measurement techniques and theoretical approaches used to explore physical processes associated with the spin-wave propagation in complex nano- and micro-dimensional magnetic structures. The results of the application of magnetic structures as circuitry in signal processing and transmission systems are discussed. In particular, results on spin wave propagation in distributed magnetic periodic structures, lumped systems, coupled waveguide structures and controllable magnonic structures are considered. Specific examples of circuitry based on magnonic structures are discussed, and possibilities for further development of this circuitry are explored.
