Abstract :
Summary form only given. Controllable radiation fields from a particle beam antenna were confirmed with computer simulations. The particle beam antenna consisted of modulated localized electron and ion beams. A typical example of the spatial profile of the potential field radiated from a cylindrical particle beam antenna was considered. The change of the specified antenna parameter was found to easily control the direction of radiated fields from the particle beam antenna. The spatial electric and magnetic fields radiated from the particle beam antenna for infinite and finite lengths in a magnetized plasma were also obtained with computer simulations
