Hi Marcus,
Thank you for your awesome answer.
I've found this online calculator http://www.rfcafe.com/references/calculators/skin-depth-calculator.htm
According to this, using Copper, for 100 mhz I'll only need a skin depth of: 6.54 μmeters or 257.59 μinches. A thickness of 0.006543 mm...
Hi, Dave,
Thank you for your answer. I'll start building just one then I'll see.
Yes I do realize, that's one of the reasons I want to use a flexible material so I can fold it when I'm not using it. I'm planning to use wood as support, like a canvas frame.
What about my questions?
- I think...
I want to build a Resonant Cavity to play with frequencies around 100-700 mhz. I'd like to try different shapes, so I was thinking in using a cheap malleable material like aluminum foil.
Questions:
- I think one layer of aluminum foil might be too thin.. If I paste a couple of layers will do...
Homework Statement
Piezoelectric crystals will change about 0.1% of their static dimension when an external electric field is applied to the material.
Homework Equations
1. What happens with the static dimension if the external electric field applied is a constant?
2. Will the static dimension...
