RECTANGULAR GAUSSIAN PULSE-PROPAGATION IN SEA-WATER

The propagation in sea water of a low-frequency electromagnetic pulse generated by an electric dipole is investigated. The electric dipole i s excited by a rectangular Gaussian pulse. The frequency-domain formul a for the downward-travelling field is Fourier transformed to obtain a n explicit expression for the field at any distance in the time domain . The propagation of a rectangular Gaussian pulse as an envelope for a low-frequency burst is also analyzed and its anomalous behaviour is d etermined. Graphs for amplitudes of a single rectangular Gaussian puls e and a burst are displayed and discussed for a range of distances.
