The conclusion shows that the nonlinear factor of electromagnetic material results in the density of stimulated current to be related to the position of the remote field.

And adopting the optimization design, high conductivity, the electromagnetic material production equipment in no-load loss low power output, more powerful, and stability, long service life.

But when supermassive black holes at the center of a galaxy feed, the material falling into them heats up, giving off a bright glow across the electromagnetic spectrum.
