The present disclosure relates to the technical field of microwave absorption, and in particular, to a multi-layer wave absorber structure and use thereof. The multi-layer wave absorber structure has a sandwich structure, and an intermediate layer of the sandwich structure is an electromagnetic loss-free dielectric layer. The electromagnetic loss-free dielectric layer includes a vacuum layer, an air layer, a paraffin layer, or a polytetrafluoroethylene layer.
