Abstract: A system for determining a characteristic of an oil well includes a signal source to generate an excitation signal during a first time duration and to generate a local oscillator signal during a second time duration. The system further includes a directional coupler, and a resonator disposed in an annulus of an oil well to receive the excitation signal through the directional coupler. The system also includes a mixer to receive a resonator signal from the resonator through the directional coupler, to receive the local oscillator signal, and to generate a mixer output signal based on the resonator signal and the local oscillator signal. The system further includes a filter to filter the mixer output signal to produce an intermediate frequency signal having an intermediate frequency, and a processor to determine a pressure or a temperature experienced by the resonator based on the intermediate frequency signal and the excitation signal.

Abstract: A downhole energy transmission system is described. The system can include a casing string having a number of casing pipe disposed within a wellbore, where the casing string has at least one wall forming a cavity. The system can also include a remote electrical device disposed within the cavity of the casing string at a first location. The system can further include a first stripline cable disposed on an outer surface of the casing string, where the first stripline cable transmits a first energy received from an energy source. The system can also include a second stripline cable disposed adjacent to the first stripline cable at the first location, where the second stripline cable is electrically coupled to the remote electrical device.
