What is it about?
Spin waves are the fundamental excitations in magnetically ordered media. Here, we present a numerical to efficiently calculate the dispersion and spatial profiles of spin waves propagating along magnetic waveguides with an arbitrarily shaped cross section and any distribution of the equilibrium magnetization within this cross section.

Why is it important?
In magnetism, there is an increasing interest in studying the effects of non-trivial sample geometry and curvature on magnetism and magnetization dynamics. With increasing geometrical complexity, analytical studies become cumbersome and computer simulations become costly. Our numerical method has been developed with these challenges in mind and will boost the study of spin-wave propagation in waveguides with complex geometry.
