The design of a reflective surface operated in the GHz range is proposed to enable beam-steering and polarization conversion simultaneously. The concept presented in this work relies on plasma-based Intelligent Reflecting Surfaces (IRS) in which the plasma is magnetized. Plasma-based IRSs have been introduced recently and consist of rectangular plasma discharges placed on top of a metallic ground plane. The reflected signal can be reconfigured electronically by varying the plasma parameters (e.g., density). First, a theoretical model is exploited to evaluate the capability of a plasma-based IRS to implement beam-steering and polarization conversion simultaneously. Second, the preliminary design of two plasma-based IRSs is presented to combine beam-steering with 1) cross-polarization or 2) linear-to-circular polarization conversion. According to the numerical results, the proposed concepts are feasible assuming the plasma density can be reconfigured in the range 4.9 × 10 17 -13.7 × 10 17 m −3 and the intensity of the magnetostatic field in the range 60-183 mT; these values are consistent with the plasma technology at the state-of-the-art. The operation frequency is 10 GHz, and the bandwidth is between 0.5-0.8 GHz for the two plasma-based IRSs presented in this work.INDEX TERMS Gaseous plasma antennas, intelligent reflecting surfaces, beam-steering, polarization conversion, linear-to-circular, cross-polarisation.

A theoretical model is proposed to preliminary assess the performance of plasma-based reflecting and transmitting surfaces. The model has been verified and, subsequently, exploited in a feasibility study to implement beam steering and polarization control. Theoretical findings laid the basis for the numerical design of a reconfigurable plasma-aided horn antenna. Notably, the solution proposed is capable of both beam steering and polarization control relying on a plasma-based transmitting surface. Specifically, the main lobe can be steered in the range 0 • − 50 • maintaining the gain > 10 dBi, the relative side lobe level < −10 dB, and the reflection coefficient < −10 dB. The bandwidth is 1 GHz for an operation frequency of 10 GHz. Polarization conversion is feasible maintaining values of the plasma parameters and magnetic induction field compatible with the technology at the state of the art.

The subject of this work is the numerical design of a plasma-based dual-band reflective surface. The proposed concept consists of a series of cylindrical plasma discharges placed on top of a reconfigurable surface made of conventional metallic patches. The possibility to independently control the steering of two signals, one in Ku-band (12.5 GHz) and the other in Ka-band (27.5 GHz), with a frequency ratio larger than 2, is proven. The signal at a lower frequency is controlled via the plasma density, while the one at a higher frequency is reconfigured via the conventional metallic surface. Notably, the larger the difference between the two working frequencies, the more a plasma-based reflecting surface suits dual-band operations.INDEX TERMS Gaseous plasma antennas; Reflective surfaces; Dual-band; Ku-band; Ka-band.
