[IEEE 2018 China International SAR Symposium (CISS) - Shanghai, China (2018.10.10-2018.10.12)] 2018 China International SAR Symposium (CISS) - Dynamic Metasurface for Synthetic Apeture Radar Imaging

摘要： In this paper, a PIN dioded loaded programmable metasurface element and dynamic apeture has been proposed. The programmable element-a complementary electric LC (cELC) resonator is patterned into the microstrip transmission line. Two PIN diodes are integrated across the capacitive gap of the cELC element, The digital states of each coding element can be controlled in real time by changing the states of PIN diodes . The proposed dynamic aperture has potential applications in dynamic beamforming, electromagnetic imaging, and security check.
