METHOD FOR CONTROL OF ELECTROMAGNETIC TERAHERTZ CARRIER WAVES

摘要

Method and apparatus for affecting, in particular for deflecting and/or for focusing of electromagnetic radiation (1, 4, 10) in the frequency range between 0.1 and 10 terahertz, wherein the radiation is affected by a large-area modulator (2, 5, 8) which has a matrix of at least 10 x 10 individually active surface elements (7), wherein each surface element (7) has a diameter greater than 5 µm and less and 100 µm, in particular about 10 µm, wherein each surface element (7) is controlled individually by a central controller and takes on one of at least two states in accordance with the control.
