Theory about a special kind of resonator

Click For Summary
SUMMARY

The discussion focuses on simulating a special resonator, specifically one with a λ/4 coupler configuration between hard-line coax and the cavity. The key to controlling its modes lies in adjusting the dimensions, which can shift performance from resonance to rejection. The resonator operates at a frequency of 7 GHz, and understanding its mode of operation is crucial for effective simulation and control.

PREREQUISITES
  • Understanding of resonator theory and operation
  • Familiarity with λ/4 coupler configurations
  • Knowledge of electromagnetic field theory, specifically H-field and E-field interactions
  • Experience with simulation tools for electromagnetic modeling
NEXT STEPS
  • Research simulation techniques for resonators using software like ANSYS HFSS or CST Studio Suite
  • Study the principles of frequency tuning in resonant structures
  • Explore the effects of dimensional changes on resonator performance
  • Learn about the design and analysis of coaxial resonators
USEFUL FOR

Engineers and researchers in the fields of RF design, electromagnetic simulation, and resonator technology, particularly those involved in the development and optimization of resonant structures.

Hello ,I have the following resonator Its very intresting.
I need to simulate it .Is there some theory regarding this resonator ? so i could control it and see which modes could be made from it?
Thanks.

Engineering news on Phys.org
The key to the mode of operation is the orientation of the end-fed, λ/4? coupler, between the hard-line coax, and the cavity.

By changing the dimensions, the performance could be moved from resonance to rejection. You would need to know the frequency of operation and the specific application before generating a model.

Where did you find it? Who made it? What party number?

Hello,I was given it to investigate without any details.
I got a mode where the H-field is which is going threw the hole of the "disk" and the E-field is surounding it
As shown below.The frequency of this mode is 7Ghz.
How do i controll the resonance frequency of this ode in such structure?
Thanks.
