Potential demodulating ability in biological tissue exposed to radio-frequency (RF) signals intrinsically requires an unsymmetrical diode-like non-linear response in tissue samples. This may be investigated by observing possible generation of the sec... Read More about Calibration model for detection of potential demodulating behaviour in biological media exposed to RF energy.
