An intelligent plasma-based protection system that transforms an electromagnetic barrier from a transparent state into a reflective state when jamming is detected, providing adaptive and real-time protection for satellite communications.” The system uses the Drude Model to calculate the required electron density and attenuation, while an ESP32 monitors the signal and detects SNR degradation. Once interference is detected, the plasma metasurface is activated. The system follows a closed-loop control framework consisting of Detection, Logic, and Actuation layers.
Project Idea
This project presents an innovative system for mitigating Radio Frequency Interference (RFI) in Low Earth Orbit (LEO) satellite communications. The concept relies on ionizing noble gases and transforming them into plasma that acts as a reconfigurable electromagnetic barrier. The barrier remains transparent under normal conditions and transitions into a reflective state when interference is detected, providing adaptive protection for satellite antennas.

The Idea
The project provides an autonomous plasma-based metasurface that acts as an intelligent barrier to protect satellite antennas from jamming signals. The system features: * Active Ionization: Transforming neon gas into a plasma state using high-voltage excitation. * Dynamic Reflectivity: Modulating electron density to control the plasma properties and create a reflective barrier. exceeding 80 dB based on the model and simulations. * Smart Feedback Loop: Detecting SNR degradation and automatically activating the protection system. * A lightweight and frequency-adaptive design compared with traditional static shielding. * A theoretical Shielding Effectiveness (SE )
