This code is based off the works of [1-3]. Make sure you have an NVidia GPU otherwise you will have to select the option of non-GPU use, which is very slow. When the code runs you should be able to visualize electromagnetic radiation propagating towards a Gaussian plasma ball, which represents a meteor. Futher analysis such as radar cross section or separation of scattered fields will need to be implemented by you.
Take note, while an ADE-PML (similiar to CPML) absorbing boundary condition is used, using this technique can introduce errors into the simulation [4]. If you find this to be an issue, you may need to implement methods as prescribed in [5] - however this particular method requires more computations and memory.
