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.

Method for controlling terahertz electromagnetic carrier waves

A method for processing received electromagnetic radiation includes receiving electromagnetic radiation having a plurality of carrier waves in the frequency range between 0.1 and 10 terahertz and having modulated onto the carrier waves information with a signal frequency of less than 50 GHz. The received radiation is filtered with a filter that is tunable in the frequency range from 0.1 to 10 terahertz so as to obtain at least one carrier wave as a terahertz signal. The terahertz signal is provided to a detection circuit that is sensitive to the terahertz signal frequency.

Method and device for processing terahertz waves

A method for producing an electromagnetic carrier wave in the frequency range between 0.1 and 10 terahertz that is suitable for the wireless transmission of data includes generating, by an electromagnetic pump wave, at least two mixing waves with a defined frequency difference, the pump wave being configured to constitute one of the mixing waves; and producing an electromagnetic carrier wave by frequency mixing the mixing waves.
