1. A coating layer for a substrate, the coating layer comprising:
a coating material having graphene and/or graphene derivatives that reflect and/or absorb an electromagnetic (EM) wave having a frequency of above 20 GHz, wherein the coating material is deposited on a surface of the substrate; and
wherein the substrate has a thickness of ¼ of a wavelength of the EM wave.
