    loop antenna design with specific magnetic field characteristics

    Thank you for the helpful schematics, I definitely need to research more into it. I also came across some material about another type of amplifier which seems to do the job. Are you familiar with "complementary symmetry push-pull" amplifiers? It seems it would allow me to amplify the signal...

    loop antenna design with specific magnetic field characteristics

    Thanks again for the response! I've read through some material, it seems that the amplified signal will always remain of a single polarity. Is it possible to amplify the signal to oscillate both positive and negative? I ask this because I would like the loop field polarity to oscillate at the...

    loop antenna design with specific magnetic field characteristics

    Thanks again for the insight! I'm moving along fairly quickly now. My next question is a little more electronics oriented for which I have limited experience. I've spec'd a signal generator which will produce the test frequencies I will be using. The problem is that the output voltage of these...

    loop antenna design with specific magnetic field characteristics

    What if I told you that is exactly what I'm trying to reproduce experimentally? I'm very familiar with Coral Castle and have actually visited the site. Ed's story correlates with some other information I've come across and as a result, has driven me to actually try and recreate his work. I don't...

    loop antenna design with specific magnetic field characteristics

    I know it sounds a bit odd, but there is a theory I would like to test which explains how it may be possible to reduce the apparent mass of an object using EM radiation of a certain "flavor". - - - Updated - - - I just realized this experiment can be likened to the physics and setup of an MRI...

    loop antenna design with specific magnetic field characteristics

    I'm not trying to detect an echo or signal in the sense of of a response emitted by the mass. Basically the mass will be situated on some sort of a scale where it can be monitored for fluctuations.

    loop antenna design with specific magnetic field characteristics

    Brad, I suppose I need to be a little more specific with what I'm trying to accomplish here. I'm investigating possible mass fluctuations of a sample of limestone that will be situated within the center of the loop. This loop needs to be small in order to produce a uniform magnetic field due...

    loop antenna design with specific magnetic field characteristics

    If I understand correctly, the main loop needs to be fed continuously with a AC of a variable frequency. I need to have current being fed into the loop because I'm investigating the radiated field characteristics on a sample mass. It is worth noting that the sample mass is innately...

    loop antenna design with specific magnetic field characteristics

    Thank you for the responses guys, I have definitely made some progress with the experimental design work. My next question is with regards to how to feed the power into the loop. It seems the overwhelming majority of sources I have read talk about feeding the loop using a small 1/5...

    loop antenna design with specific magnetic field characteristics

    Hello, I come from a mechanical engineering background. I am looking to set up an experiment that requires the use of a custom loop antenna. I am not using this antenna for transmitting or receiving. I am only interested in the characteristic magnetic field that would be produced when the loop...
