Abstract
An electromagnetic wave absorption structure includes at least one electromagnetic wave composite absorbing layer. The electromagnetic wave composite absorbing layer includes a conductive composite layer and an insulating layer. The insulating layer is stacked and overlapped with the conductive composite layer. The electromagnetic wave absorption structure can provide good electromagnetic wave absorption function, and have the features of light and thin, so it is particularly suitable for satisfying the electromagnetic wave absorption or shielding requirements of thin electronic products.
