Theory about a special kind of resonator

Click For Summary
The discussion revolves around a unique resonator that requires simulation to understand its operational modes. Key factors influencing its performance include the orientation of the end-fed, λ/4 coupler and the dimensions of the resonator, which can shift its behavior from resonance to rejection. The user has identified a mode at 7 GHz where the H-field passes through the disk's hole while the E-field surrounds it. To control the resonance frequency, knowledge of the operational frequency and application specifics is essential. Further details about the resonator's origin and specifications are needed for accurate modeling and control.

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.

Thread 'RF magnetic field generation'

Hello! I want to generate an RF magnetic field at variable frequencies (from 1 to 20 MHz) using this amplifier: https://www.minicircuits.com/WebStore/dashboard.html?model=LZY-22%2B, by passing current through a loop of current (assume the inductive resistance is negligible). How should I proceed in practice? Can i directly connect the loop to the RF amplifier? Should I add a 50 Ohm in series? Thank you!
