Image 2: Image symbolizing electrically switchable nanoantennas. The part of the nanoantenna with the lightning from top looks metallic, with metallic luster when it is electrically charged. The part of the nanoantenna without the electric lightning looks transparent, like a glass, when it is not charged.
