A Tunable Electromagnetic Bandgap Structure Using Plasma
Abstract
tunable electromagnetic-bangap (EBG) structure based on a double layer slotline using plasma is proposed. The plasma permittivity can be tuned by the electron density. The idea of integrating periodical plasma elements inside the slot to tune the stopband is investigated. An electron density and an electron collision frequency equal to 1.75 10 13 cm -3 and 10 10 s-1 respectively, are the plasma parameters selected in this study. The simulations reveal a shift rate of the second stopband equal to 6%. A new conØguration of the structure is also proposed to adapt it better to the experimental requirements. Based on the simulation results, adding the plasma elements to the modiØed conØguration shifts the stopband 4% and reduces its bandwidth by 43% (at° 20dB).
