The invention provides a plate-type electromagnetic/acoustic fusion metamaterial, a composition and an aircraft, and relates to the technical field of metamaterials, the plate-type electromagnetic/acoustic fusion metamaterial comprises an acoustic functional structure and an electromagnetic functional structure, the electromagnetic functional structure is connected to the acoustic functional structure, the acoustic functional structure regulates and controls sound waves incident on the acoustic functional structure, and the electromagnetic functional structure regulates and controls electromagnetic waves incident on the electromagnetic functional structure. The basic unit of the plate-type electromagnetic/acoustic fusion metamaterial is mainly designed and prepared under the centimeter scale, the requirement for machining precision is low, and the basic unit is very suitable for industrial batch production. The plate-type electromagnetic/acoustic fusion metamaterial has the characteristics of light and thin structure and multifunctional regulation and control of electromagnetic waves and acoustic waves. Compared with the prior art, the method has the remarkable advantages of additional weight, space occupation and application cost, and the problems of functional interference, economical efficiency reduction and the like caused by the fact that an electromagnetic shielding material and a sound absorption and insulation material are used in an aircraft in an overlapped mode at present can be effectively solved.
