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.
