I put "soliton pulses in a plasma" in a search engine and everything that came back was well above my head.

Does anyone have a link to something that explains this in plain language?

In a plasma (or certain nonlinear media) a wave will not diminish in size. Its why waves in shallow seas can go for hundreds of miles unchanged, why light pulses in fibre optic cables can cross the ocean bottom without diminishing to noise. These waves are called solitons. It was my EE Professor's (Lonngren) favorite research topic back in my undergraduate days
