Abstract
The use of elementary quanta of magnetic excitation---magnons, or spin waves---as carriers of information attracts more and more interest, as transferring the magnetic moment (spin) of an electron without transferring its electric charge avoids the heat generation inherent in CMOS technology. This study aims to exploit directed spin-wave propagation in a structure composed of parallel stripes of thin-film yttrium iron garnet, forming an asymmetric three-dimensional coupler geometry. This approach has the potential to enhance the density of functional elements in three-dimensional magnonic networks.
