Abstract
Chapter 4 treated the resonant frequencies, dispersion relations, and mode fields for various magnetostatic modes. In this chapter we expand on the properties of magnetostatic waves in thin films and describe how to excite them. We first establish approximate expressions for the Poynting vector and energy velocity valid in the magnetostatic approximation. Next we apply the phenomenological description of magnetic damping introduced in Chapter 2 to the problem of magnetostatic wave attenuation. Finally, we derive orthogonality and normalization conditions and use these relations to calculate the excitation of magnetostatic waves by thin wires and conducting strips.
