摘要：
The dispersion relation of magnetostatic waves tangentially magnetized to saturation ferrite film, with a "magnetic wall" condition (tangential component of microwave magnetic field is equal to zero) on one of the film surface and with a metal condition on the opposite surface is analyzed. The dispersion characteristics show that unidirectional magnetostatic waves appear in this structure: they can transfer energy in one direction only and fundamentally cannot transfer energy in the opposite direction. The dispersion-free propagation of magnetostatic waves also is possible in the structure in a wide frequency interval. (C) 2005 Elsevier B.V. All rights reserved.
