Abstract: An apparatus for a coaxial transmission line is provided. The apparatus can include a dielectric member having an inner surface defining a bore along a longitudinal axis of an inner conductor of the coaxial transmission line; and a first conductive member mounted axially around the dielectric member and extending along the longitudinal axis. A cross-section of an outer surface of the first conductive member can define a first perimeter. A cross-section of an inner surface of the outer conductor of the coaxial transmission line can define a second perimeter. The first perimeter can be smaller than the second perimeter and thereby provide clearance between a portion of the outer surface of the first conductive member and the inner surface of the outer conductor of the coaxial transmission line when the apparatus is positioned in an annulus defined by the inner conductor and the outer conductor of the coaxial transmission line.

Abstract: A method for sound wave generation includes sensing one or more characteristics of a sound wave; calculating an inverted sound wave based on the one or more characteristics; and emitting the inverted sound wave by flowing a current, selected according to the inverted sound wave, through a wire under tension that passes through a positive pole of a magnet and a negative pole of the magnet, thereby causing the wire to vibrate.

Abstract: An apparatus and method for electromagnetic heating of a hydrocarbon formation is presented. The apparatus is a radio frequency antenna module in a radio frequency antenna for delivering electromagnetic energy generated by a generator into the hydrocarbon formation. The antenna module comprises: a conductive member; at least one conductive sheath with a first and second end surrounding at least one portion of the conductive member; at least one electrical coupler electrically coupled to the conductive member and the at least one conductive sheath for receiving the electrical energy; and an electrically insulating seal inserted at the first and second end of each of the at least one conductive sheath between the conductive member and the conductive sheath to maintain an enclosed cavity defined by the conductive member, the conductive sheath and the electrically insulating seal.
