Tuning anapole resonator question

[yefj]

Hello , I have designed an anapole resonator which works great at 10GHZ,With the mode shown below.
However when I try to increase the frequency of this mode by decreasing the inner circle it didnt went so well.
Video is attached ,could you please help me understand how to increase the frequency of this mode and increase its coupling?
Thanks.

I was wondering if you could briefly describe for us the operation of the device. Thank you.

Hello tech99,I made a video for you explaining the situation.
I just can find a good way to increase frequency all methods are barely increasing the frequency .
Thanks.
