Abstract:
A multi-directional resonant-type electromagnetic wave absorber includes: at least one ground layer; a first dielectric layer and a second dielectric layer respectively formed on different outer surfaces of the ground layer; a first resistive pattern layer formed on an outer surface of the first dielectric layer; and a second resistive pattern layer formed on an outer surface of the second dielectric layer. Herein, the electromagnetic absorption performance is adjusted by changing one or more of thicknesses, permittivities, and permeabilities of the dielectric layers, thicknesses of the resistive pattern layers, and a reflection coefficient of the ground layer.
