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 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
