A STUDY ON THE APPLICATION OF NiZnCu FERRITE AS MAGNETIC FEEDER IN ELECTROMAGNETIC TRANSMITTER

Detection of hydrocarbon in shallow and deep sea water currently uses the sea bed
logging (SBL) technique, which uses a transmitter to conduct an electromagnetic
signal to a hydrocarbon reservoir andtravel the signal backto the receiver. The signal,
which is received by the receiver, becomes weakdueto the hydrocarbon's depth. This
problem exists due to the weakness in a transmitter's performance that could not
travel the EM signal to the depth of the hydrocarbon location. In order to solve this
problem, a magnetic feeder was attached to the transmitter (antenna) in order to
increase the amount of magnetic field around the antenna. NiZnCu Ferrites material
was used as a magnetic feeder due to the magnetic properties of the material. Several
characterisations were done to characterise the material. Thermogravimetric (TGA),
X-Ray Diffraction (XRD), Field emission Electron Scanning Microscope (FESEM)
and High Transmission Electron Microscope (HRTEM) were used to study
temperature of heat treatment, nanostructure and nanosize of the material.
