Main research findings
Plasma is composed of charged particles that interact with magnetoelectric fields. The motion of these particles is highly complex, making the study of plasma physics a challenging endeavor. It is estimated that 99% of visible matter exists in the plasma state, highlighting the importance and fascination of researching this topic to better understand our surrounding world.
However, the intricate processes within plasma complicate its study. Conducting experiments or deploying observational instruments to collect environmental data is often expensive, requiring significant development and maintenance of specialized equipment. Fortunately, advancements in modern computer technologies have introduced an alternative research method: simulating processes using numerical methods.
This thesis examines a specific class of numerical methods used to study plasma instabilities and assess how different magnitudes and directions of magnetic fields influence the development of these instabilities. By discretizing the mathematical equations in both time and space, these numerical methods facilitate detailed analysis. Further research focused on enhancing and evaluating the stability of the proposed numerical schemes under various parameters.
The findings of this work have potential applications in large-scale studies of plasma instability in areas such as the ionospheric physics and astrophysics, providing valuable insights for future scientific and technological advancements.
