Abstract
The present disclosure provides a method for long range communication through underwater and underground environments by converting encoded message data into spherical coordinates and rotating a magnet about axes of rotation corresponding to those spherical coordinates at a transmitter. A receiver configured to detect the magnetic dipole field of the generated electromagnetic wave can thus determine the orientation of the magnetic dipole, deduce the spherical coordinates, and decipher the encoded data. A system comprising a mechanical antenna transmitter and receiver with a magnetic field sensor arrangement for carrying out the method is also provided.
Claims19
A method of communication via extremely low or ultra-low frequency electromagnetic waves, the method comprising the steps of:
- (a) at a transmitter:
- receiving message data to be transmitted;
- encoding the message data using a pre-defined encoding method;
- dividing the encoded message data into one or more encoded data packets;
- converting each encoded data packet into a spherical unit vector co-ordinate having an inclination angle and an azimuthal angle within a range representing the encoded data packet;
- and
- for each encoded data packet, generating a low frequency wave by rotating a magnet or electromagnet, or rotating a magnetic field of a set of electromagnets, about an axis of rotation corresponding to the respective spherical unit vector coordinates for that data packet, the axis of rotation of the magnet or electromagnet, or of the electromagnetic field generated by the set of electromagnets, acting to modulate the magnetic field of the wave;
- and
- (b) at a receiver:
- receiving the low frequency wave;
- determining the axis of rotation of the magnetic field of the wave for each data packet by analysing a magnetic dipole field of the wave;
- converting the spherical coordinates for the axis of rotation into the encoded data packets;
- and
- decoding and reconstructing the message data using the pre-defined encoding method.
