Improving coupling of a resonator by looking at surface currents

AI Thread Summary
The discussion focuses on improving the coupling of a resonator by analyzing surface currents. The user observes varying surface current responses at weak and strong coupling levels and seeks guidance on enhancing coupling in their model. The potential relevance of the Q-factor is mentioned, indicating its importance in assessing the resonator's performance. Understanding the relationship between surface currents and coupling efficiency is crucial for optimization. Effective coupling can lead to better resonator functionality and performance.

Hello , In the system below there is a mode i am trying to couple.
at weak coupling I get a certain surface current responce and in stronger coupling I have different responce as shown below.
How can I see from the surface currents where can i improve the coupling in my model?

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
