Simulating Magnetized Plasma using an Accelerated Finite Element-Boundary Integral Code

• This paper describes an accelerated finite element-boundary integral code with support for complex media. The code is implemented in Python using several open source packages, and uses Numba just-in-time compilation for improved performance. To accelerate the boundary integral part of the code, a multilevel implementation of the adaptive cross approximation is used. As a numerical example, scattering against a magnetized plasma is demonstrated. For this example, compression of boundary integral matrices is achieved to 9 % of the memory required for full matrices.
