PARTICLE_IN_CELL SIMULATION TO STUDY THE PROPAGATION OF ELECTROMAGNATIC WAVES IN PLASMA

This study uses a numerical approach to investigate the propagation of electromagnetic (EM) waves in plasma. We begin by developing a One-dimensional (1-D) electrostatic particle-in-cell

(PIC) code and validate its accuracy through the well-known two-stream instability, serving as a benchmark for our implementation. Building upon this foundation, we extend our work to a Two-dimensional (2-D) electromagnetic PIC code, leveraging insights gained from the 1D simulations. The 2-D Kempo code is then used with change in the diagnostic tools to align with the specific objectives of our research to examine EM wave propagation in plasma under three distinct conditions: 1. unmagnetized plasma, 2. magnetized plasma, and 3. magnetized plasma with an inhomogeneous density profile.
