Millimeter wave diagostics are essentiell for fusion plasmas, since they work without plasma contact.

Both reflectometry and scattering diagnostics greatly benefit from fullwave simulation of the interaction between plasma and wave.

The fullwave code IPF-FD3D is a synthetic Doppler reflectometer on top of plasma turbulence simulations.
IPF-FD3D is a 2D or 3D finite difference time domain code for cold magnetised plasmas. It is written in C, with post-processing done in python.
