Reproducing continuous radio blackout using glow discharge plasma

Area of Science:

• Plasma physics
• Electromagnetics
• Wave propagation

Background:

• Simulating plasma sheaths is crucial for understanding electromagnetic wave interactions.
• Existing methods may not offer large-scale, continuous plasma generation.

Purpose of the Study:

• To introduce a novel plasma generator for large-scale, continuous, non-magnetized plasma.
• To investigate electromagnetic wave propagation through the generated plasma.
• To assess the suitability for simulating plasma sheaths and related applications.

Main Methods:

• Utilized a low-pressure glow discharge to excite plasma within a 30-cm-diameter hollow structure.
• Conducted electromagnetic wave propagation experiments across UHF, L, and S-bands.
• Measured electron densities ranging from 10^9 to 2.5 × 10^11 cm^-3.

Main Results:

• Successfully generated large-scale, continuous, non-magnetized plasma.
• Reproduced continuous radio blackouts in UHF, L, and S-bands.
• Observed results consistent with theoretical predictions for wave propagation.

Conclusions:

• The novel plasma generator is effective for simulating plasma sheaths.
• The method supports research in communications, navigation, and electromagnetic mitigation.
• Applicable for antenna compensation studies in plasma environments.
