March 2024: A new version of Wavesim was released on February 27 in github. The main feature of the new version is the use of  a CUDA based acceleration module (cumex), that can provide speed-up optimisation of up to x2 times.

Reference [1] below is the main reference for WaveSim, introducing the modified Born series approach for the Helmholtz equation, which was later generalized to vector fields. Reference [2] introduced a modified fast Fourier transform that enabled having an ultra-thin boundary layer, significantly reducing the computational costs and memory requirements.
