Japanese scientists invent the color that blocks Wi-Fi signals

By mixing iron-oxide particles in color, researchers have invented the color that blocks radio frequency in the highest spectrum where Wi-Fi and other higher bandwidth communications occur.

Although most Wi-Fi technologies work on 2.4GHz and 5GHz, special colors can block frequencies up to 100GHz, researchers said.

A 200GHz block color is under development.

Here’s how it works: metal particles in the color resonate at the same frequency as Wi-Fi and other radio waves, so the signals can not go through the thin layer of pigment.

In this way, a secure wall is created that stops the signals from entering the house and from the walls covered with a special color.

Use for such an innovative product is already present. Theaters have been interested for some time to find a legal way to block phones during shows.
