Real-Time Near-Field mmWave Measurements Using Screen-Printed Metasurfaces and IR Camera
This article elaborates on a technique for rapid real-time imaging of millimeter-wave (mmWave) power density over surfaces of several wavelengths in size. The approach involves using a screen-printed metasurface equipped with elements designed for absorption of mmWaves, along with an infrared (IR) camera to monitor temperature changes due to the absorption. By modulating the transmitted signal and
