|Electric field magnitude of the TE0,3 mode in a gyrotron at 42 GHz.|
This is just one example of the current popularity of gyrotrons as a research topic. Gyrotrons are promising with potential to fill the terahertz gap that currently exists for RF sources. We have recently added new features to CST STUDIO SUITE® that are designed with the special features of gyrotrons – for example, the very high mode number of operation – and we are certain that simulation will contribute the understanding and optimization of these promising devices.
The picture above shows the electric field which has been generated by the beam exciting the wave in the cavity of a 42GHz gyrotron. The TE0,3 mode is then finally propagating out of the taper section, as can be nicely seen by the field patterns there.
