本文提出了一种基于人工完美匹配层概念的空间太阳能卫星微波能量接收方法。通过将整流二极管嵌入到精心设计的超材料电池中，所获得的整流表面同时表现出与空气和整流电路近乎完美的阻抗匹配，以及在谐波频率下与空气的强阻抗失匹配，从而使结构简单，可以使用商用多层印刷电路板技术实现。实验结果表明，在0.1 mW/cm2的入射功率密度下，该整流表面的厚度接近自由空间波长的1/40，实验功率吸收率达到99.92%，对二阶谐波的抑制能力为56.16 db。实测的整流效率与理论预期相符。通过引入无源功率合成器网络的附加层，该方法也可用于收集弱环境射频和微波能量的应用。我们期望在未来从这个新颖的概念中出现广泛的应用。
In this paper, we propose a microwave energy reception approach for space solar power satellite applications based on the concept of artificial perfectly matched layer. By embedding rectifying diodes into well-designed metamaterial cells, the obtained rectifying surface simultaneously exhibits a nearly perfect impedance matching to the air and the rectifying circuits, and a strong impedance mismatching to the air at harmonic frequencies, leading to a simple structure that can be implemented using commercial multi-layer printed circuit board technology. The fabricated sample shows that, with a thickness of nearly 1/40 of the free-space wavelength, this rectifying surface has an experimental power absorption rate of 99.92% under normal incident power density of 0.1 mW/cm2, and a 56.16-dB suppression to the second-order harmonic. The measured rectifying efficiency complies well with the theoretical expectation. By introducing an additional layer of passive power combiner network, the proposed approach can also be used in applications of harvesting weak ambient RF and microwave energy. We expect a wide range of applications to emerge from this novel concept in the future.
