摘　　要：文章基于人工完美匹配层(PML)的电磁特性提出了一种新型的可用来实现能量完美匹配接收的高效整流天线板,并从仿真上给予了验证。该整流天线板同时拥有与空气完美匹配的阻抗以及超高效的能量吸收特性,仿真结果显示1/80空间工作波长厚度的整流天线板即可吸收转化垂直入射电磁波99%以上的能量,该技术可广泛用于当今各种频段的微波能量传输与接收装备研发应用领域。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 relative 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, resuiting 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.
