abstract

  • This article presents a parametric study using full-wave simulations about the potential
    use of cold plasma discharges to achieve frequency reconfiguration on a Sievenpiper mushroom
    metasurface. The study was done by inserting plasma tubes in between the patches of the mushroom
    structure, in three different positions with respect to the top of the metasurface, and varying the
    electronic density while keeping the plasma collision frequency. The obtained results show that it is
    possible to shift the stop-band generated by the metasurface around 25% towards lower frequencies
    for an electron density value inside the tubes of 1014 cm􀀀3, when they are placed in between the
    top patches of the metasurface. Additional insertion losses are exhibited when operating near the
    plasma frequency.
