A method for wireless data transmission between a transmitter and a receiver includes modulating signals onto an electromagnetic carrier wave in a frequency range between 0.1 and 10 terahertz, and transmitting the carrier wave by the transmitter and focusing the transmitted carrier wave in the direction of the receiver. The transmitter is aimed towards the receiver by an adjusting system using a wireless communication link between the transmitter and the receiver so as to provide automatic aiming.

Wireless data transmission with terahertz waves

A method for influencing electromagnetic radiation in a frequency range between 0.1 and 10 terahertz includes providing a planar modulator having a matrix of at least 10&#xd7;10 individual, active planar elements. Each planar element has a diameter between 5 &#x3bc;m and 100 &#x3bc;m. The planar elements are individually controlled using a central control unit such that each planar element assumes a respective one of at least two states in accordance with the control so as to influence the radiation.
