Improving coupling of a resonator by looking at surface currents

Click For 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 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
