Abstract: An array of non-thermal plasma emitters is controlled to emit plasma based on application of an electric current at desired frequencies and a controlled power level. A power supply for an array controller includes a transformer that operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The controller monitors reflected power characteristics, such as harmonics of the alternating current, to determine initiation voltage of the plasma and/or resonant frequency plasma emitters. The array of non-thermal plasma emitters may be used in therapeutic, diagnostic, and/or medical sanitization applications, including where a non-thermal plasma treatment regimen is prescribed.

Abstract: A detection device for detecting and characterizing biological energy fields emitted by biological specimens is configured to collect and analyze an electromagnetic signal that includes millimeter-length waves generated by the interaction of atmospheric plasma with torsion waves of the biological energy field. The device performs spectral analysis on the millimeter waves to determine characteristics of the corresponding torsion waves that generated them. An array of several hundred non-thermal plasma plumes are placed directly in front of a circular horn. A switchable circular polarizer is used to select left hand circular, linear or right hand circular polarization. A low noise frequency converter allows a noise temperature of less than 1150 K. A frequency scan and averaging algorithm is developed to characterize noise temperature versus frequency, comparing signal and noise levels between plasma on and plasma off, and switching polarization sense.

The power into the array is monitored by the controller and can be adjusted by the user. The controller monitors the phase relationship between the transformer primary winding voltage and the gate drive voltage, and adjusts the drive frequency to resonance. Alternatively the balanced driver is configured as an oscillator which drives the transformer at resonance by default. A signal from the transformer driver generates an interrupt to the controller for synchronizing current and voltage measurements for power control.

Abstract: An AC power supply drives and controls an array of non-thermal plasma emitters at desired frequencies at a controlled power level. The power supply comprises a step-up transformer, a balanced driver, and a controller. The transformer operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The balanced driver may be driven directly by the controller.

Alternatively the balanced driver is configured as an oscillator which drives the transformer at resonance by default.

Abstract: A plurality of non-thermal plasma emitters is disposed on a rigid or flexible substrate. The rigid substrate enables the device to be pre-formed in any shape and the flexible substrate enables the device to conform to any surface topography at the time of treatment. The substrate is a dielectric material and in a preferred embodiment is made of thin FR-4. Each of the plasma emitters has a drive electrode on one side of the substrate and a ground electrode on the opposing side of the substrate. In the preferred embodiment both electrodes are centered over a through-hole in the substrate. A conductive drive track is connected to each drive electrode and a conductive ground track is connected to each ground electrode. A drive terminal is connected to the drive track and a ground terminal is connected to the ground track.
