Abstract :
This paper presents a time domain scheme that predicts spinwave resonances in magnetic materials. The proposed scheme incorporates the Landau-Lifschitz equation of motion (LLE) including losses and exhange effects with the traditional Yee scheme. With uniform rf mode excitation, spinwave resonances for a simple structure are observed.
