Apparatus and method for radio frequency spectroscopy using spectral analysis

摘要: A source of high frequency electromagnetic radiation is coupled to a specimen containing target chemical whose presence and/or concentration be ascertained. Preferably, the includes plurality spectra. The via probe pair that also used access return signal representing an interaction between and specimen. processed yield spectral signature correlating its concentration. An apparatus for performing analysis comprises conductive probes (6), display system (20) oscillators (50, 58), microprocessor (74), phase detectors (72, 92) neural network (100). In preferred embodiment, human finger pressed against pair, glucose. invention thus permits lay user determine his or her own glucose level.
