In one embodiment, controlling the spatial distribution of an electromagnetic field in a system involves determining an inflection frequency for energy applied to the system below which a first spatial distribution results and above which a second spatial distribution results, selecting an excitation frequency to be used to generate an electromagnetic field to be applied to the system based upon the determined inflection frequency, and applying an electromagnetic field generated using the selected excitation frequency.

Systems and methods for controlling the spatial distribution of an electromagnetic field

Cell or tissue permeability to electrical signals can be used to determine the depth of anesthesia of a patient. A method and device is presented to measure, record and control the effects of anesthesia or analgesics on humans and/or animals. Based on impedance values of tissues measured at single, multiple, or a domain of frequencies, the system detects tissue permeability alterations as determined by electromagnetic, impedance, and/or dielectric spectroscopy. The system measures the permeability of tissues to electrical signals and correlates these values to the depth of anesthesia or sedation level of a certain tissue or individual. This method and device can be used to measure the effects of anesthesia or analgesic for either local or systemic administration.
