DIPOLE-TYPE SOURCE FOR GENERATING LOW FREQUENCY PRESSURE WAVE FIELDS

Disclosed are directed to dipole-type sources and associated methods and systems. A dipole- type source may comprise a first bender plate and a second bender plate. The dipole-type source may further comprise a first cavitycoupled to the first bender plate and a second cavitycoupled to the second bender plate. The dipole-type source may further comprise one or more drivers in fluid communication with the first cavity and/or the second cavity, wherein the one or more drivers are operable to drive a respective fluid between at least one of the one or more drivers and the first cavity and between at least one of the one or more drivers and the second cavity, such that the first and second bender plate oscillate at least substantially synchronously in the same direction to generate an up-going wave and a down- going wave with opposite polarity.
