The dynamic magnonic crystal: New horizons in artificial crystal based signal processing

In this chapter, we describe the development and properties of the first experimental dynamic magnonic crystal devices and highlight certain aspects of the intriguing new physics that they have to offer us. We discuss the significance of the dynamic magnonic crystal both in the context of the furtherance and technological application of magnonics, and in the understanding of general wave dynamics in metamaterial systems. © Springer-Verlag Berlin Heidelberg 2013
