Concept: Superconductivity is one of many resonant tunneling transmission effects. The tunnel diode has been pressed to work at THz frequencies, but it might better be used for power transmission at lower frequencies. Microwave (or RF or ELF) resonant transmission would provide a lossless transmission path for power transfers.

Tunnel Diode Resonator - If the circuit is designed properly and thermally stabilized the time resolved uncertainty in the resonant frequency can be on the order of 0.005-0.05 Hz. We typically operate at about 20 MHz. Just taking orders of magnitude, 10 MHz is 107 Hz and 0.01 Hz is 10-2 Hz. This means we can know our resonant frequency to about 1 part in a billion. If we are only concerned with frequency changes on the order of 1%, then the change in frequency is directly proportional to the change in inductance. The change in inductance is directly proportional to the change in the magnetic susceptibility of the sample. When all the constants of proportionality are taken into consideration, the final sensitivity of our system is on the order of 10 parts per billion.
