electromagnetic spectrum

In addition to domains like sea, air, land, and space, or harder-to-see domains like cyberspace and the electromagnetic spectrum, these operations also take place in time, of course.

This kind of attack involves military tools on land, air, and in space, as well as communication across the electromagnetic spectrum.

All these lie on the electromagnetic spectrum, and wavelengths aside, there’s fundamentally no difference between them.

This energy tapping is possible across the electromagnetic spectrum.

It’s entirely possible that distant civilizations could be sending out similar signals, or even trying to transmit messages on purpose, since they’ll be dealing with the same electromagnetic spectrum that we are.

Landsat satellites carry sensors that record “light,” or portions of the electromagnetic spectrum, as it reflects off the Earth.
