Hi Aziz,

That confirmed my thoughts I will stick with your coaxial design and do some more field testing next year MERRY CHRISTMAS and a VERY HAPPY NEW YEAR.

When I get more time, I'll add the coaxial designs to the comparison graph.

Merry Christmas and a happy new year to you and your family Ian.

Thanks for all your work Aziz. Its looks most impressive. Well done!  respect

Can you tell me how accurate (close to reality) such theoretical calculations are?
Are there major variables that can't be estimated or anticipated?

Have a Happy, Peaceful & Safe Christmas and New Year!

Hi Huego,

you (and all the others) are welcome.

Even the coil analysis takes enormous time and work, I like to share good ideas. That was the reason, why I didn't give the coil software for free to be able to ensure the free share of coil ideas (controlled by me). I could have turned it into many $$$, but I didn't do this.

The coil models are simplified to speed up the simulation time. Nevertheless, they are quite accurate for comparisons. Well, I do trust in my work. If someone isn't trusting on me or my work, there is a simple rule: make it and see it (proof)!

It all depends on the realised circuit and one can make it worser than the theoretical expectation offers (the variables and limitations, which aren't taken into consideration).

Merry X-mas and a happy new year to all.
Cheers,
Aziz

After a long absence I see Aziz has returned to the tech forum and will be following his postings with interest.
 
Unfortunately he left this forum but left many wonderful detailed diagrams such as those displayed in this thread.

His colourful coil field diagrams were great and I believe him to be a pioneer in regards to the spiral / flat wound and DOD types coils.

Hi guys,

we can continue with analyzing coil ideas of course. But it will take some time, until I remember how to do it.

Hey Aziz!!

Great to see you back again. You will remember the coil ideas for sure, maybe over a beer or two.
Welcome home!
