In this paper, we propose an artificial surface that can receive microwave energy with high rectifier efficiency based on the theory of artificial perfectly-matching layer ( PML) , which has been validated in simulation. The effective rela-tive permittivity and permeability of the surface are matched, mostly imaginary-valued, and far greater than unity. These conditions allow the impedance of the surface completely matched to air, and produce extremely high rectifier efficiency, re-sulting in a 99% power receiving at normal incidence and within a layer thickness about 1/80 of the free space wavelength.This technology can be widely used in the areas of microwave transmission system.
