Abstract

The invention is a device to place in incision into matter (32) with a harmonious plasma cloud. A radio frequency generator system (10) produces electromagnetic waveform which is transmitted by an active transmitter incising electrode tip (28). This electromagnetic wave is utilized to initiate a plasma cloud with processes such as thermal ionization, and a photoelectric effect which then triggers an avalanche effect for charged atomic particles at the surface of the active transmitter incising electrode tip (28). This electromagnetic wave is impedance matched, frequency matched, power matched, tuned to the plasma in order to sustain, control a harmonious plasma cloud which demonstrates reduced atomic particle turbulence, and chaos while forming a coating over the surface of the active transmitter incising electrode tip (28). The magnetic bottle effect, the pinch effect, and the tunneling effect are employed to trap, contain, compress, contour, focus, and amplify the energy of the incising plasma cloud.

Operation - Figs 1 to 2
Our invention for incising matter is different from all prior devices for tncismqmatter. An on-off button / on-o.ff switch (14) is used to activate or deactivate aradiofrequency switch (12). This therefore regulates the transmission of an output signal ofa radio frequency signal generator (10)· Output signal oi a radiofrequency signal generator(10) is further controlled such that its transmission is activated or deactivated by a burs* 9 produced by expensive and high energy consumption systems such as lasers or elaborateplasma etching chambers. The levels of atomic particle turbulence and chaos manifestedby classic electrocuttine or electrosurgical units are employed tv us as-a rTafive standardfor defining an increase or decrease in atomic particle turbulence cr chaos in nlasma.
Our system employs an inexpensive, electronic radio frequency generator/amplifiersystem to produce, condition and transmit a continuous or pulsed electromagnetic fieldfrom an incising electrode tip (28). The cycle time of the electromagnetic field pulsedmode is variable and each complete on-off cycle of the pulsed mode may be as short as0.000001 of a second. Specific parameters of this electromagnetic field generator systemare largely determined by the atomic particle composition along the interface of theincising electrode tip (28) and the matter into which an incision is placed (32). Our systemutilizes the atoms along the interlace of the incising electrode tip (28) and the matter intowhich an incision is ulaced (32) to generate a plasma cloud as opposed to systems whichrequire an ionizable gas to be injected into the field of incision and Thereupon have theinjected gas enspized and converted into plasms.

11 that they possess less atomic particle chaos and a higher order of organization than seen inplasma arcs of classic electrocutting systems thereby allowing our device to generate aharmonious plasma cloud.
The levels of atomic particle turbulence and chaos manifested in classicelectrocutting or electrosurgical units are employed by us to create a relative standard orbaseline from which we may define and demonstrate an increase or decrease in themagnitude of atomic particle turbulence or chaos in plasma.
The effects of electromagnetic wave frequency and electromagnetic wave power orfield strength are interrelated and dynamic. Nuclear Magnetic Resonance teaches us thatprecessing atomic particles may absorb radiant electromagnetic energy when that atomicparticle precession frequency and the frequency of the radiant electromagnetic energy arcin resonance. In other words, Nuclear Magnetic Resonance demonstrates that efficientabsorption of electromagnetic energy occurs when the atomic particle is frequencymatched to the radiant electrcmagnetic wt ve frequenev, Our device demomutte;analogous relationship regarding the importance of frequency mmehing oir tr?nsnfi;wrelectromagnetic wave to the atomic particle properties composing tin plasma cloudsurrounding the incising ek-ctrodc tip (28).
Nuclear Magnetic Resonance also teaches us that the prequency or atom:. .r oOprecession may be directly related to the strength of the magnetic field in which the atomicparticle exists. Therefore, the stronger the applied magnetic field, the higher theelectromagnetic field frequency required to achieve the resonance needed for efficientenergy absorption. Likewise, the electron gyrofrequencies in the ”D" and “E” layers of theearth's ionosphere substantially increase as we move from the equator toward themagnetic poles of the earth, either north pole or south pole. Respecting similar scientificprinciples, our device addresses the Issue of field strength and electromagnetic frequencyand thereby power matches and frequency matches our transmitted electromagnetic waveto the atomic particles composing the plasma cloud coating the incising electrode tip (28).Nonetheless, individual parameters of our electromagnetic field generator system varysubstantially when placing an incision into different types of matter and are substantiallydependent upon the atomic particle composition along the interface of the incisingelectrode tip (28) and the matter into which an incision is placed (32). - , '·. . a . ” . 1 . ’ , y 1 , ι··..ιϊcii ·. , e!e:r e .

As the electromagnetic field traverses the thin coating of harmonious plasmasurrounding the activated incising electrode tip (28\ the electromagnetic field is slowlydamped or decreased in amplitude. Finally, the electromagnetic field will pass completelythrough the plasma cloud and will encounter matter outside of the intended incision path,namely the matter which surrounds the cloud of incising plasma. According to thephysical chemistry principle of Tunnelling, the generated electromagnetic wave thenencounters a barrier to which it is not tuned nor impedance matched and thereby asubstantial percentage of the remaining energy of the electromagnetic wave is reflectedback into the harmonious plasma cloud. This reflected electromagnetic energy acts tofurther energize the molecular particles in the plasma cloud, thereby reducing the outputenergy which must be transmitted by the electromagnetic wave generator system. Thisprocess also serves to minimize the percentage of total electromagnetic radiation thatpenetrates into, that reacts with, and that presents potential radiation exposure damage tomatter outside of the intended incision path,

Furthermore, the Pinch Effect vvhicn has burn usco tor ma-7years in fields such as plasma physics is employed in our system. lit tins way, we are ableto compress, contour, shape and control the harmonious plasma cloud whh a sc lid cohollow transmitter incising electrode tip (28). We also employ the Magnetic Bottle Effectused in fields such as nuclear physics to trap and contain the compressed plasma cloudwithout the need of solid matter containment vessels and thereby avoid the requirement toemploy hollow or cavity containing incising tip probes to trap and control the plasmacloud. Increasing the density of atomic particles in the harmonious plasma cloud allowsus to substantially increase the plasma cloud power density, thereby improving the cuttingefficiency and power of the plasma cloud.
Furthermore, comoressing the plasma cloud causes a substantial decrease in the cross sectional diameter of the plasma cloud thereby decreasing the width cf the intended incision path as well as minimizing side effects or potential adverse impact on matter outside of the intended path of incision.
