Abstract
This chapter focuses on the dynamic properties of nanowires. It shows how the properties of nanowires change from a single nanowire (or a large ensemble of noninteracting nanowires) to a strongly interacting nanowire system. The dominating role of the long-range magnetostatic dipolar interactions is demonstrated in establishing a configurational reorientation transition. The interaction of magnetic nanowires with electromagnetic waves (EMWs) leads to a specific spin-wave excitation spectrum due to its size and shape sensitivity. Magnetic nanowires are serious contestants for novel microwave devices, based on the propagation of EMW in the nanostructure. The results of modeling the electrodynamic diffraction problem show how the properties of these flexible systems of ordered magnetic nanowires can be tuned up to the THz frequency range.
