摘要
A combined ME composite structure is made of several cylindrical layered composites in series or parallel connection.Due to the cylindrical structure,the combined structure does not need more space.The characteristics of multi-resonance frequencies have been studied.Each resonance frequency of the structure can be adjusted by changing the cylinder diameter of the corresponding cylindrical layered composites.The number of resonance frequencies increases as the number of cylindrical layered composites increases.The multi-resonance frequencies behavior makes these cylindrical layered composite structures suitable for applications in multifuctional devices with multi-frequencies operation.
