Abstract

Abstract: A tri‐band phase switched screen is proposed based on a dual‐band artificial magnetic conductor (AMC) for radar cloaking. The electromagnetic band gaps of the AMC structure can shift from a dual‐band working state, that is, 2.44 and 3.65 GHz, to another dual‐band of 3.56 and 6.01 GHz, by adjusting the biasing current on the four PIN diodes. Based on the AMC structure above, a potential tri‐band PSS is realized through different switching schemes, and therefore achieves good stealth effects during the three bands above.
