摘要	Systems and methods in accordance with embodiments of the invention implement electrically tunable metasurfaces. In one embodiment, an electrically tunable metasurface reflectarray includes: a mirrored surface; a conductive layer; a dielectric layer; where the conductive layer and the dielectric layer are in direct contact, and thereby define a conductor-dielectric interface; a plurality of subwavelength antenna elements; and an electrical power source configured to establish a potential difference between at least one subwavelength antenna element and the mirrored surface; where a potential difference between a subwavelength antenna element and the mirrored surface applies an electric field to a corresponding region of the electrically tunable metasurface reflectarray; where any applied electric fields in conjunction with the geometry and the material composition of each of the subwavelength antenna elements, the conductive layer, and the dielectric layer, enable the electrically tunable metasurface reflectarray to measurably augment the propagation characteristics of incident electromagnetic waves.
其他摘要	根据本发明实施例的系统和方法实现电可调超线曲面。在一个实施例中，电可调超线面反射阵列包括：镜面;导电层;介电层;其中导电层和介电层直接接触，从而限定导体 - 介电界面;多个亚波长天线元件;电源，用于在至少一个亚波长天线元件和镜面之间建立电位差;其中，亚波长天线元件和镜面之间的电位差将电场施加到电可调超线面反射阵列的相应区域;其中任何施加的电场结合每个亚波长天线元件，导电层和介电层的几何形状和材料成分，使得电可调超线面反射阵列能够可测量地增加入射电磁波的传播特性。
