AI Thread Summary
An anapole resonator has been successfully designed to operate at 10GHz, but attempts to increase its frequency by reducing the inner circle have not yielded positive results. The creator is seeking assistance in understanding how to effectively raise the frequency of this mode and enhance its coupling. A video has been provided to illustrate the current operation and challenges faced. Despite various methods attempted, frequency improvements have been minimal. The discussion focuses on troubleshooting and optimizing the resonator's performance.

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.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
