In this master thesis we develop a versatile computational tool, the Dynamic Matrix Method, that enables a systematic study of the propagating spin waves normal modes of a wide class of extended ferromagnetic nanostructures. A generalization of the method to account for magnonic crystals is included. We provide a detailed analytical treatment of the magnetic dipole-dipole interaction. The method was applied in the study of differente kinds of magnetic systems, with an emphasis on understanding the physics behind spin wave non-reciprocal phenomena. The results obtained in this work showcase the potential of the Dynamic Matrix Method as a powerful research tool in magnonics and other related areas.
