Reflective Phase Shifter Based on Active Metamaterial

The paper proposes a design of a reflective phase shifter based on an active metamaterial. On the basis of the performed electrodynamic modeling, the main parameters of the phase shifter were calculated, as well as the patterns of the electromagnetic field. The obtained dependences show the effectiveness of the proposed metamaterial structures for controlling the phases of electromagnetic waves at the output of the structure, while it is possible to achieve a wide range of phase changes, small losses in the process of switching the operating modes of the structure.
