Elektromagnetic

As the electromagnetic wave propogates through the sea, the electrical component of the wave is conducted away from the magnetic part, rendering it powerless; in effect the wave departs from itself.

These are my presentation notes from the Maxwell City workshop in June this year.

Extremely low frequency transmitters were developed for communication with deeply submerged submarines at depths of more than 200 metres and under polar ice-caps. Submarines below this depth are undetectable by radar and other non-acoustic systems.

I’ve always been into submarines and ships, and basically anything that is big, metallic and man-made with an engine. From my grade C in physics and the realisation that ‘I ain’t no Einstein’, I allowed my working life to direct my interests. Two of my early career choices were apprentice mechanic and HGV driver, where I viewed myself as a practical pioneer of women’s rights to work in jobs that were at that time, mainly dominated by men.
