Abstract: A system and method for separating oil from an oil tailing having water includes introducing the oil tailing within a chamber, and applying RF energy to the oil tailing at a temperature sufficient to convert the water to steam and to separate the oil from the tailing. The system allows removal of the water from the tailing followed by RF energy absorption by the tailing prior to substantial heat transfer to the surrounding mineral portion of the tailing. Among other advantages, the system produces tailings substantially devoid of oil, thereby allowing the tailing to be disposed of in an environmentally safe manner. The system is particularly advantageous for offshore drilling operations where storage and subsequent hauling of the oil tailings ashore for processing and disposal is expensive.

Abstract: A soil remediation system heats contaminated soil by generating a rotating sub-surface electromagnetic field. The system includes three electrodes disposed 120 degrees apart on a remediation circle. These electrodes are excited by AC voltages with 120 degree phase differences relative to each other. This results in the generation of a sub-surface traveling wave that propagates in a circumferential direction.

Abstract: A grain containment vessel equipped with one or more antennas and a vapor extraction system is disclosed. An electromagnetic heating pattern is established throughout the grain volume elevating the bulk temperature, while an air flow is applied throughout the grain volume. The electromagnetic energy desorbs the water and increases the vapor pressure and the air flow carries the heat and water from the containment vessel. A controlled amount of electromagnetic energy is introduced into the grain volume to reduce or eliminate fungus infestation and increase insect mortality.

Abstract: To treat and diagnose tissue, a radiating antenna system is positioned within the tissue to radiate electromagnetic energy into a portion of the tissue desired to be heated, and a plurality of antenna elements are positioned for receiving and/or reflecting the radiated electromagnetic energy from the radiating antenna system. In certain applications, one or more of the antennas has an interior volume for receiving a heat exchange fluid to change the temperature of the tissue proximal to the receiving element.

Abstract: A medical treatment system includes an antenna for radiating energy from a source of electromagnetic energy and including a first radiating element and a second radiating element having a conductor helically wound and coaxially positioned around the first radiating element to receive energy radiated by the first radiating element. The first and second radiating elements are positioned substantially along a longitudinal axis of the antenna with the first radiating element having a proximal end coupled to the source of electromagnetic energy. With this arrangement, energy from the electromagnetic source is efficiently conveyed from the first radiating element and then resonates the coaxially positioned and helically wound second radiating element.

Abstract: A method and system is provided for autogenic generation of a subterranean fluid flow, such as may be applied, for example, to enhance oil recovery or pollution abatement. In general, the method and system includes placing an electromagnetic apparatus down the borehole of an applicator well, and radiating energy into a permeable formation to achieve displacement flooding effects.

Abstract: Medical systems and instruments which utilize microwave energy to provide heat treatment and diagnostic imaging of tissue are provided. One medical treatment system for treating tissue includes an antenna having a radiating element configured to transmit electromagnetic energy toward a desired area of the tissue and having an interior volume for receiving a heat exchange fluid, thereby changing the temperature proximal to the desired area of the tissue.

Abstract: Medical systems and instruments which utilize microwave energy to provide heat treatment and diagnostic imaging of tissue are provided. One medical instrument has a collinear array having antennas configured to transmit electromagnetic energy so that the transmitted energy, in aggregate, is directed toward a desired area of the tissue. Another microwave medical system includes a catheter having an inflatable balloon in fluid communication with an inflation source, and an antenna having a radiating element positioned within the inflatable balloon to transmit electromagnetic energy toward the desired area of tissue. Still another medical instrument includes an antenna having receiving elements for receiving electromagnetic energy radiated from an electromagnetic source, rectifying devices, each having a first end electrically connected to a corresponding one of the receiving elements; and a transmission line electrically connected to a second end of each of the rectifying devices.

Abstract: Methods and apparatus for treating containers holding mixed wastes and regions of the earth contaminated with radioactive materials or mixed waste provide for extracting one of non-radioactive or radioactive materials from the contaminated volume. The method also includes using a phase-modulated multiple antenna system for treating larger near-surface volumes and for creating steerable and variable heating patterns. The radio frequency antenna apparatus can be used for volatilizing non-radioactive materials from containers or volumes of the earth and disposing of them in a safe and controlled manner.
