A resonant cavity can farthest keep the field distribution of its own mode, and the coupling between two resonant cavities is very small.It shows
When individually to 1 feed-in microwave of the second resonant cavity, the S parameter of whole system, it can be seen that pass through the reasonable design window degree of lip-rounding
The matched well of resonant cavity may be implemented in formula；Meanwhile the S12 of system is very small, show system from the second microwave source 4 to
The coupling of first microwave source 6 is very small；Vice versa；
In addition a job is respectively shown in two resonant cavities in microwave electric field center, another work in microwave magnetic field
Field part when center.Illustrate when the second resonant cavity 1 work in magnetic field center, individually feed situation lower chamber in field
