Abstract:
A non-resonant electromagnetic energy sensor comprising:(a) housing having wall members surrounding a path of travel of an analyte, said wall members defining a chamber having an interior volume for passage of said analyte therethrough, at least a portion of said chamber including at least one measuring region defined by a dielectric region disposed between evanescent regions;(b) a non-resonant electromagnetic energy circuit, said circuit comprising:(i) a voltage source;(ii) a voltage regulator;(iii) at least one electromagnetic energy source in communication with said interior volume of at least one of said measuring regions, said a least one electromagnetic energy source generating electromagnetic energy having electrical and magnetic components of non-equal total peak values;(iv) at least one electromagnetic energy detector in communication with said interior volume of at least one of said measuring regions, said at least one electromagnetic energy detector producing an output signal upon detection of signal variations in said electromagnetic energy within at least one of said measuring regions caused by passage of said analyte therethrough.
