| Abstract: |
| The influence relationships between mechanical structure factors such a
s surfaces and joints in different locations and unloaded Q value of resonant ca
vity are researched. First, by using the medium electrical parameters abou
t RF effective conductivity and concentrated contact impedance, the
hierarchical relationship model of mechanical structure factors and unloaded Q v
alue of resonant cavity is established. Furthermore, based on simulation analysi
s, the key mech
anical structure factors are identified, and the influence relationships b
etween medium electrical parameters and unloaded Q value are discovered. F
inaly,a new formula including multi-factors weight model is provided which can b
e
used to compute unloaded Q value more accurately. |
