Underwater communications using electromagnetic waves

Objective

This project is based upon the discovery that there is a transmission window for electromagnetic (em) waves for propagation through seawater. The use of em waves has several advantages over acoustic waves, which are the only technique presently available for data transmission through seawater. These advantages are faster velocity, longer wavelength and higher frequency. It has been shown theoretically and by preliminary experiments that em waves within a frequency range 1 to 10MHz will be able to propagate distances up to 1000m. These properties of em waves allows data to be propagated with high bit rates up to 1Mbits/sec This high rate will allow compressed video images to be propagated at standard camera frame rates (25Hz). Therefore a series of basic experiments on em wave propagation will be undertaken to quantify em wave propagation through seawater.
