RT Journal Article T1 Potential use of cold plasma discharges for frequency reconfigurability in a sievenpiper mushroom metasurface A1 Pizarro Torres, Francisco Guillermo A1 Stuardo Oyanedel, Pablo A1 Olivares Veliz, Ricardo A1 Rajo Iglesias, Eva AB This article presents a parametric study using full-wave simulations about the potentialuse of cold plasma discharges to achieve frequency reconfiguration on a Sievenpiper mushroommetasurface. The study was done by inserting plasma tubes in between the patches of the mushroomstructure, in three different positions with respect to the top of the metasurface, and varying theelectronic density while keeping the plasma collision frequency. The obtained results show that it ispossible to shift the stop-band generated by the metasurface around 25% towards lower frequenciesfor an electron density value inside the tubes of 1014 cm-3, when they are placed in between thetop patches of the metasurface. Additional insertion losses are exhibited when operating near theplasma frequency.
