The feeder link between FES and the satellite is in Ku band, while the link between mobile terminals and satellite is in L band.

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

First of all, electric fields are not an electric current that is coursing through the tissue.

And that current, electrical current, is carried by electrons, just like in your house and so on.

Radiotelescope

Your computer uses this presence of current to represent a one, and the absence of current to represent a zero.

Other studies of ionospheric currents used magnetometer arrays deployed by scientists from Boston College, Augsburg College, and the University of Michigan.

Radio could carry sound without wires.

We're seeing lots of different possibilities, lots of different funding models

That means that the magnetic pulse is generating an electric current that's interfering with the erroneous electrical activity in the brain.

The way we transmit wireless data is by using electromagnetic waves in particular, radio waves.

This electrode here, called the gate, controls the flow of current from the source to the drain these two electrodes.

Radio waves. There's another thing.

And radio waves are limited.

In Denmark, fluctuations in electricity trade, as driven by precipitation and water runoff in Scandinavia, lead to higher variations in emissions than fluctuations in temperature.

If you run current through them, you can run 1,000 times more current through one of these than through a piece of metal.

So, electricity is the flow of electrons inside a material.

Downlink emissions could be particularly damaging and already the emissions of some satellite systems had severely curtailed radio astronomy observations.

21. Remote sensing observations make use not only of visible light, but also of several other regions of the electromagnetic spectrum, such as the infrared, thermal and microwave regions.

These radio waves penetrate through walls.

Whenever current flows through the coil, this becomes an electromagnet.

The only magnetism comes from electric charges and currents.

The AC adapter has been unplugged, switching to battery mode.

And we could also produce power cables, to transfer enormous amounts of current between power stations.

Hyperspectral imaging these systems acquire data over a range of wavelengths in the visible, short and long wave infrared (thermal) regions of the electromagnetic spectrum.

This is actually a brainwave sensor that's reading the electrical activity of my brain as I give this talk.

And light is part of the electromagnetic spectrum.

That blue line there is my brainwave.
