In general, this can be optimized by block-iterative methods.

Another related idea is to use Compressive Sensing, which employs a more efficient basis for incident and scattered angles (instead of plane waves). A nice overview is given in L....

This paper is also relevant. It uses fast-multipole method for near-to-far-field transformation in the FDTD and ray tracing. G. Tang et al., “Enhancement of the computational efficiency of the near-to-far...

This can probably be done with [fast spherical Fourier transform](https://www-user.tu-chemnitz.de/~potts/nfft/nfsft.php), but this assumes that we have only scattered fields already in far-field. But, in reality, we start with dipole fields...

Niko, thanks for creating this issue. We have been thinking about it for some time, the related issues are #6, #114, #282 . To sum up, here are the main...

And I think that any simple test is better than none. So the simplest would be ``` cd src/ make seq cd ../tests/2exec ./comp2exec seq ``` but the problem with...

Another acceleration method for such problems is using multi-level fast-multipole algorithm to compute interaction between different particles (and keep FFT for internal calculations), see De Zaeytijd J., Bogaert I., and...
