The high-frequency properties of small 3D ferromagnetic elements are investigated by means of micromagnetic simulations. The dynamic susceptibilty spectra associated with two types of submicrometer-size elements: a cylindrical dot with a vortex state and an eye shape particle with a bidomain state are reported. In these confined structures, the spectra reveal a rich variety of modes which are identified.
