APPARATUS AND METHODS FOR THE CHARACTERIZATION OF THE DIELECTRIC RESPONSE OF FLUIDS

摘要

A method for characterizing the dielectric response of a fluid includes receiving the fluid into a portion of a flow line that is disposed proximate to a photonic bandgap (PBG) resonant cavity so that a dielectric permittivity of the fluid affects a frequency response of the resonant cavity. The method further includes providing electromagnetic waves to the resonant cavity and measuring a frequency response of the resonant cavity in the presence of the fluid in the flow line. The method further includes determining a property of a resonant mode of the resonant cavity using the frequency response and determining a property of the fluid using the property of the resonant mode.

1. A system for characterizing a dielectric response of a fluid, the system comprising:
a first photonic bandgap (PBG) resonant cavity comprising a first resonant frequency, wherein the resonant cavity is configured to be electromagnetically coupled to a flow line so that a fluid within the flow line affects a frequency response of the resonant cavity; a wave generator electromagnetically coupled to the resonant cavity; and a signal analyzer configured to measure the frequency response of the resonant cavity.
