Electromagnetic Smart Screen for Tunable Transmission and Reflection Applications
Electromagnetic smart screen (ESS) containing conductive strip or patch array loaded with pin diodes was investigated with experimental approaches. Transmission and reflection coefficient were measured with free space method and validated by finite element simulation. Tunable transmission coefficient was found from ESS between 3 to 8 GHz which can be used as smart radome or modulator. Tunable reflection coefficient of a layer of ESS with thickness about 0.575mm on top of metallic substrate is observed between 3 to 4 GHz. The effective working bandwidth can be up to 20％ of the central frequency, which is much wider than metamaterials which are not tunable.
