Having worked on many types of resonant systems over the years(electrical, mechanical, acoustic), this chart is very useful to get a intuitive grasp on the some of the parameters and values needed for a basic LC (inductor, capacitor) electrical resonant system. It covers 100 Mhz to 1 Khz, I hope you find it useful, regards Arto.
I hope you consider, purchasing a copy of my book, so I can continue to create content like the one above, Regards Arto

Hi, Many Thanks Arto for your unique works.
1. Could you please double check in the above LC chart if Henry is in Micro or nano.
2. How to optimize L and C for a required Frequency; i.e there are so many L and C that would give the required F, but how do I select the optimum C or L to achieve the best Oscillation.

Thank you Abdelaal, it looks like I mislabeled the jpeg file, this has now the correct version.
Regarding the best choice, I would start with working out the coil with the least resistance, thus getting a higher Q (Quality of magnification). This might not always be practical, I would suggest finding the combination that will give you a self resonant coil, where the capacitance required is what the parasitic component of the coil that cannot be removed. This will give you a single system, a coil only, where the calculations can be quite complicated. The best option here is to test a few coils on hand and find where they self resonate (frequency), by using my calculations you can work out what the self-capacitance of the coil is. Do try and wind a coil to the wave length or a multiple, or even a 1/4 or 1/2 these type designs you will find are the best options.
Regards Arto.

Hi, your chart at bottom right says 2500000nH = 0.25H, but in fact it equals 0.0025H does it not?

Hi James, sorry I didn’t update this part, I did have it different iterations, it was an artifact from an old edit. All is fixed, thanks, regards Arto.
