    Abstract : The goal of nuclear fusion research is to create a clean and virtually limitless energy source. In order to that, a plasma must be heated to hundreds of millions degrees Celsius. A commonly used heating mechanism is ion cyclotron resonance heating, where antennas emit radio waves into the plasma. READ MORE

  3. 3. Modeling of Current Drive with Radio Waves on DEMO

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Erik Gåvermark; [2018]
    Keywords : ;

    Abstract : In fusion reactors, one has to make sure that the plasma does not come in contact with the reactor wall. This is done by accelerating electrons within the plasma creating a current. One method to do this is to transmit radio waves into the plasma from antennas which are located in the reactor wall. READ MORE

  4. 4. Planar Antennas for Terahertz Detectors

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Zakir Hossain; [2012]
    Keywords : ;

    Abstract : The use of the millimeter-wave and terahertz (THz) systems are becoming very important in various scientific and military applications. In many applications i.e. radio-astronomy, THz imaging, remote sensing, secure communication links, THz radars, plasma diagnostics etc. READ MORE
