  • Eigenmode frequencies are similar but HFSS seems to be slightly further off measured values. S parameter measurements with HFSS proved to be difficult, so used MWS instead. S parameters and Q factors seem to vary in their similarity to the measured values.

  • Comparing these plots to those found in Ctf3Prototype1, the dipole frequency in these simulation are seen to be less than those measured, as well as Q factors. The power at the resonant frequency is similar to that in the measurements. In the simulation there seems to be little variation in the curve for different ports, possibly due to the absence of imperfections found in the actual cavity.

Monday 29th October - Friday 9th November

Started with HFSS and Microwave studio packages.

  • Eigenmode frequencies are similar but HFSS seems to be slightly further off measured values. S parameter measurements with HFSS proved to be difficult, so used MWS instead. S parameters and Q factors seem to vary in their similarity to the measured values.
