I have not considered using a maser as a potential solution. Though I do think you might be able to make a case for converting the analogue acoustical frequency somehow, and transmitting it to a receiver that will convert it back into the original tone.
I will say that the anti-electronic...
This is not meant as a criticism to any of the other commenters, but personally I like how methodically @Baluncore has decided to approach the issue. That said, I urge all commenters to consider the basics before jumping right into building your systems.
What kind of energy are you putting into...
Consider the following thought experiment...
You are an engineer with a very peculiar assignment. With a mind to reduce the investment of excessive human labor and material waste, you have been asked to build an apparatus similar to an old-fashioned voicepipe. You are asked to ensure that the...
To dispel some theories: When the primary coil has no input the secondary coil registers no output. Furthermore, as the input voltage is increased in the primary coil voltage output increases in the secondary coil.
Conductivity between coils: There is no contact between the coils, or...
I wasn't wearing anything metallic (t-shirt, basketball shorts, running shoes, no jewelry), nor was I wearing a grounding bracelet.
I don't think its my body's iron content, and I'll tell you why. I had a partner help me move two long, high-grade ferrite bars toward the poles of the transmitter...
I have these two very large (ferrous core) coils,
They are basically identical, each 200mm long and have a diameter of 100mm. The core is medium grade steel
One coil is receiving an input of 8V(peak-to-peak) @ 4 MHz from the function generator. The second coil is placed 1m away, and is...
