General phenomenological theory of magnetic spin waves in ferromagnetic media is originally reformulated and applied to analysis of magnetostatic waves in films and plates with arbitrary nisotropy under arbitrary external field. Exact expressions are derived for propagator of linear waves between antennae (inductors) and mutual impedances of antennae, and exact unified dispersion equation is obtained which describes all types of magnetostatic wave eigen-modes. Characteristic frequencies (spectra) and some other important properties of main modes are analytically considered and graphically illustrated. Besides, several aspects of non-linear excitations and magnetic-wave chaos are discussed, including two-dimensional "non-linear Schrodinger equations" for magnetostatic wave packets and envelope solitons.
