---++ Preliminary
  • Step file of BPM received from Igor, imported into CST, cannot run eigenmode solver with lossy materials.
  • Recreated the geometry which allows scalability and can now export as a stl file for GdfidL. (It is also rotated 45 degrees about z axis to make positioning ports in GdfidL easier.
  • Ran eigenmode simulation of the original geometry and got the results shown below. With the dipole mode polarisations highlighted.

Solution Frequency (Hz)
1 2.95e9
2 6.75e9
3 6.86e9
4 7.50e9
5 7.53e9
6 9.83e9
7 1.03e10
8 1.17e10
9 1.18e10
10 1.24e10

  • These values are much lower than expected. The file was designed with a 12GHz dipole frequency in mind.
