“…Comparison between the calculated distribution and the estimated density from the LIVPD graph reveals an approximately 8.5% discrepancy between the results. For experimental validation, plasma density distribution is estimated based on phase difference measurements along the column using a phase difference detector microchip, as introduced by the authors in [6]. The resulting measurements align with the LIVPD graph-derived estimates, with a similar 8.5% discrepancy.…”

This paper introduces an innovative method for quantitatively determining plasma density in plasma columns, with particular applicability to reconfigurable antennas. This method significantly enhances the speed of capturing density variations, particularly in surface wave-excited antennas. By utilizing images of excited plasma tubes, the proposed approach extracts a light intensity versus plasma density (LIVPD) graph, creating a direct correspondence between visible light intensity and plasma density. The methodology, encompassing LIVPD graph extraction and plasma density evaluation, is comprehensively elucidated. Rigorous analytical and experimental validations confirm a minor deviation of approximately 8.5%. The versatility of the method is demonstrated through two practical applications, reaffirming its accuracy in challenging scenarios. Additionally, this study includes a comparative analysis that highlights the superiority of the method in terms of sampling rate, measurement points, and non-intrusiveness over conventional techniques. This paper thus presents a robust method with promising potential for accurate plasma density determination in diverse antenna applications.INDEX TERMS Plasma antenna, image processing technique, plasma density, determination of the plasma density, surface wave.

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.

“…The foundational concept of a reconfigurable solid-state plasma antenna was originally proposed by Fathy et al [6] in 2003. This concept offers a significant level of operational flexibility and enhanced integration compared to a gas-state plasma antenna [7][8][9][10][11][12][13][14][15]. Subsequent advancements in this field have been characterized by notable contributions.…”

This article examines the feasibility of integrating solid-state plasma surface p-i-n (S-PIN) diodes into on-chip slots using silicon-on-insulator (SOI) technology. Two categories of solid-state plasma S-PIN diodes are characterized. Simulations analyze the current-voltage (I-V) characteristics, carrier concentrations, potential distribution, and thermal considerations of both single and dual S-PIN diodes, with optimization of their structural parameters and sizes. Experimental tests on fabricated S-PIN diodes of varying sizes with bias lines embedded in the on-chip slots show favorable I-V characteristics for both types of diodes. The measured results closely align with simulation predictions for the diodes' conduction onset voltages. Additionally, a cavity-backed slot antenna (CBSA) is proposed to evaluate and compare radiation characteristics resulting from integrating different types of S-PIN diodes.
