The invention provides an electrothermal film and stealth metamaterial composite structure with a rasterized wave-transparent design and a preparation method of the electrothermal film and stealth metamaterial composite structure. Comprising a grid structured electric heating layer (1) and a wave-absorbing stealth layer (2) composed of a magnetic material wave absorber (21) of a step structure and a metal grounding layer (3). The wave-absorbing stealth layer (2) is arranged at the lower end of the grid structured electric heating layer (1); a step structure magnetic material wave absorber (21) of the wave-absorbing stealth layer (2) is connected with the grid structured electric heating layer (1); the metamaterial wave absorber (21) is composed of an array structure formed by periodically arranging a plurality of same magnetic material units. The invention also relates to a preparation method of the composite structure. The metamaterial wave absorber disclosed by the invention has the characteristics of magnetic loss, multi-resonance of a step structure, a step edge diffraction effect and the like, and can realize efficient absorption. The metamaterial wave absorber structure provided by the invention has the advantages of small structure thickness, simplicity in processing and the like.
