3D printing metamaterials for highly efficient electromagnetic wave absorption

Metamaterials (MMs) with artificial structures have extraordinary physical properties that cannot be found in traditional materials. MMs electromagnetic wave absorption (MMAs) can prepared through the structural design and arrangement of unit special properties. These at subwavelength scale are fundamental for MMAs to surpass performance limits bulk materials, so matching manufacturing processes is particularly important. The rapidly developing three-dimensional (3D) printing technology has shown great advantages potential complex materials structures, providing a simple, rapid, efficient method researching preparing MMAs. In this review, we introduce concept development focus on research status using 3D manufacture Furthermore, briefly their typical applications, discuss inadequacies current limitations MMAs, propose prospects combination printing.
