Plasma-Based Reflective Surface for Polarization Conversion

This study analyses, for the first time, the use of reflective surfaces based on magnetized plasmas for polarization conversion. The feasibility of this concept has been assessed via a theoretical model. Moreover, the numerical design of a plasma-based reflective surface is presented. The latter enables linear-to-linear (LP-to-LP) and linear-to-circular polarization (LP-to-CP) conversion over a broad frequency range, from 7.5 to 13 GHz. To this end, the applied magnetic field intensity has to be tunable over 55-140 mT and its direction steerable toward three mutual orthogonal axes. At the same time, the plasma density has to be controlled up to 2 x 10(18) m(-3). These requirements are consistent with the plasma technology at the state-of-the-art.

Automated summary

This study examines the use of magnetized plasmas for polarization conversion on reflective surfaces, and presents a theoretical model to assess its feasibility. The study also includes the numerical design of a plasma-based reflective surface capable of linear-to-linear and linear-to-circular polarization conversion over a wide frequency range. The design requires a tunable magnetic field intensity of 55-140 mT and control of plasma density up to 2 x 10(18) m(-3), which align with current plasma technology advancements.
