k-vector distribution of magneto-static spin waves excited by micro-fabricated antenna structures
In this article we examine the k-vector distribution of magneto-static spin waves which are excited by microfabricated antenna structures. Changing the repetition of the antenna structures from a simple coplanar wave guide like structure to a meandering type antenna the k-vector distribution can be adjusted to a more or less peaked distribution representing the pitch of the meander. However, intrinsic damping of the magnetic system counteracts this effort.
