摘要：A submersible electromagnetic (EM) field generator for seafloor

electromagnetic surveying comprising an AC to DC converter operable to generate a DCoutput from an AC input and a switching module operable to generate a waveform

driving signal by selectively switching the DC output. The EM field generator alsocomprises an antenna that is operable to generate an EM field in response to thewaveform driving signal. This design approach of using a switched DC source allowssquare or rectangular wave EM signals to be generated which have sharp transitioncharacteristics and which are substantially independent of the AC input characteristics.
