New Solvers for the fullwave reflectometry code IPF-FD3D

  • For the 2D version
  • Hexagonal grid: finite difference time domain (FDTD) scheme exists for vacuum, need to add plasma effects, UPML absorbing boudary conditions
  • 4th order methods: central differences in time and space AND coupling to plasma, simultaneous 4th order (simultaneous may not be possible)

Numerical investigation of poloidal correlation reflectometry

  • Microwave beam sent to plasma with several receiving antennas
  • Each receiving antenna defines different beam geometry, probing a different poloidal position
  • Correlation of signals from different positions yields poloidal rotation direction or the pitch angle of magnetic field lines
  • Turbulence from codes can be used as input for realistic scenarios

Investigations for quasi-optical mitre bends

  • Mitre-bends are the typical waveguide components for highly oversized waveguides because they are more compact than continuous bends
  • For moderately oversized waveguides, diffraction effects can partly be compensated with quasi-optical designs
  • Quasi-optical mitre-bends can accurately be calculated with PROFUSION.
  • The work consists of parameter studies for different ratios of wavelength and waveguide diameter and the investigation of the broadband performance.
