A theoretical investigation of the emerging field of magnonics is proposed here. We have the ambition to continue to develop a simulation package for performing accurate and efficient simulations of magnetization dynamics, with special focus on magnons and their potential in information tecnology. These simulations are based on an atomistic description of the magnetisation, and the dynamics, and offer an excellent spatial resolution. We will in our simulations consider magnons excited by the so called spin-transfer torque, and explore the most efficient ways to make such excitations, and to be able to control the different modes (propagating and stationary) that emerge. Furthermore, the transport of propagating modes in magnonic wave-guides will be considered, to investigate geometries and materials specific information which enables as dissipation free transport as possible. The possibility to perform logical operations using magnons, in device structures, will finally be considered, hence exploring a technology which have potential for lower power consumption and a natural means to scaling down to extremely small units.
