I am a physics student with very limited experience in electronics and I have been tasked with making an receive coil for use in an MRI machine. The design of an RF coil amounts to constructing to what essentially amounts to an LC resonator with a set resonance frequency. The design of my coil is somewhat similar to this http://web.stanford.edu/~jbarral/Coil_RcTx.jpg [Broken] Though I have a two capacitors in series between A and B rather than the single capacitor in this illustration. My question is, current cannot flow through a capacitor but if I connect a network analyser across E and F a signal passes through the circuit, how does that work? Im certain the answer is simple but I cannot find the answer. Thank you in advance.
