使用薄超材料吸收器作为传感器阵列来测量入射到吸收器表面的无线电波的二维功率和相位分布。插入蘑菇型超表面上的表面贴片之间的集总电阻器用于吸收谐振频率的入射波。由于每个电阻器上感应的电压与沿其的电场分量成正比，因此通过监控二维电阻器阵列上的各个电压，可以获得入射波的幅度（功率）和相位分布并将其可视化为二维图像。
A thin metamaterial absorber is used as a sensor array to measure the 2-d power and phase distributions of radio waves incident on the surface of the absorber. Lumped resistors inserted between the surface patches on a mushroom-type metasurface are used to absorb the incident wave at the resonance frequency. As the voltage induced on each resistor is proportional to the electric field component along it, the amplitude (power) and phase distributions of the incident wave are obtained and visualized as 2-d images by monitoring the individual voltages on the 2-d array of resistors.
