  • Reconfigurable wideband phase-switched screen based on artificial magnetic conductor
    Patent number: 11489265
    Abstract: The present invention discloses a reconfigurable wideband phase-switched screen (PSS) based on an artificial magnetic conductor (AMC). Gap capacitance between patches is controlled by changing the capacitance of varactors, so that periodic units have a plurality of continuous frequency points. A phase difference between two adjacent frequency bands is 143°-217°, so that the periodic structure absorbs incident electromagnetic waves in a wide frequency band, and the broadband PSS is implemented with a relative bandwidth of 45.2%. The AMC structure according to the present invention is simple in structure and easy to process, with a thickness less than one twentieth of the working wavelength, and greatly reduces size and costs.
