1. A method for producing an effect of a chemical or biochemical agent on a system, comprising:

  • (a) generating a plurality of low-frequency time-domain signals by performing (i), (ii), (iii) and (iv);

    (i) placing a sample containing the chemical or biochemical agent in a container having both magnetic and electromagnetic shielding,(ii) injecting noise into the sample at a given noise amplitude;

    (iii) recording an electromagnetic time-domain signal composed of sample source radiation superimposed on the injected noise, and(iv) repeating (ii)-(iii) at each of a plurality of noise levels within a selected noise-level range,(b) analyzing the plurality of time domain signals generated in (a) by producing spectral plots of the plurality of time-domain signals, and identifying an agent-specific time-domain signal based on information in said spectral plots, and(c) exposing the agent-responsive system to the agent-specific time-domain signal identified in (b) by placing the system within the magnetic field of an electromagnetic transducer, and applying said identified agent-specific time-domain signal to said electromagnetic transducer at a signal amplitude and for a period associated with the chemical or biochemical agent sufficient to produce in the system an agent-specific effect on the system,wherein the analyzing includes;

    (i) generating a histogram that shows, for each event bin f over a selected frequency range within the range DC to 8 kHz, a number of event counts in each bin, where f is a sampling rate for sampling each of the plurality of recorded electromagnetic time domain signals, assigning to the histogram, a score related to the number of bins that are above a given threshold; and

    selecting the agent-specific time-domain signal from the plurality of recorded time-domain signals based on said score;

    (ii) autocorrelating each of the plurality of recorded electromagnetic time domain signals, generating an FFT of the autocorrelated signal over a selected frequency range within the range DC to 8 kHz, assigning to the FFT signal, a score related to the number of peaks above a mean average noise value, and selecting the agent-specific time-domain signal from the plurality of recorded time-domain signals based on said score;

    or(iii) calculating a series of Fourier spectra of each of the recorded electromagnetic time-domain signals over each of a plurality of defined time periods, in a selected frequency range between DC and 8 kHz, averaging the Fourier spectra;

    assigning to the averaged FFT signal, a score related to the number of peaks above a mean average noise value, and selecting the agent-specific time-domain signal based on said score.
