About the project
This project aims to harness non-thermal plasma’s interaction with electromagnetic waves to dynamically control radar cross-section (RCS) for military applications.
"Plasma’s ability to absorb or reflect electromagnetic waves, dependent on electron density, makes it effective for enhancing or reducing RCS in defence. Building on prior advancements in atmospheric plasma with adjustable electron density, this research will integrate non-thermal plasma technology with printed electronics to create a flexible plasma generator that can conform to various vehicle surfaces.
The project’s key objective is to design a versatile electrode system through printed electronics, enhancing plasma source flexibility and scalability for complex geometries. Traditional rigid plasma sources limit application to flat surfaces, whereas advances in printed electronics enable adaptable configurations for consistent plasma generation over non-planar surfaces.
Additionally, the project will focus on optimizing plasma generation in a diffuse discharge mode, which offers greater uniformity and stability than filamentary mode, critical for RCS manipulation. Maintaining stable diffuse discharge requires precise electric field control and specific operating conditions. High-voltage pulses of nanosecond duration will be used to ensure uniform plasma generation, preventing transition to filamentary mode.
This research will contribute to defence technology by developing a flexible, adaptable non-thermal plasma source that provides precise RCS control, advancing electromagnetic wave manipulation for stealth and defence systems.
