Scattering and reflection of microwave beams in fusion plasmas

Microwave beams have a broad range of applications in nuclear fusion, and a rigorous mathematical modeling of their propagation in plasmas is of great interest. In the mathematical framework of semiclassical methods, recent progresses in both code development (the IPP code WKBeam) and theory (Hagedorn wave packets) open the possibility to address and finally solve two open problems: (I) the effects of plasma turbulence on wave beams and (II) the efficient numerical simulation of cut-off reflections.
