Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

Ordinary and extraordinary wave couplings in the vicinity of the cutoff surfaces in magnetized plasmas are analyzed in a two-dimensionally inhomogeneous tokamak-like geometry. It is demonstrated that the mode conversion may be of an essentially two-dimensional nature when the cutoff surfaces intersect in space along a certain line. For the latter case the reduced wave equations in the transformation region are derived and solved analytically. Structures of the transformed and reflected waves and corresponding transformation coefficients are obtained for an arbitrary field distribution in the incident beam. In particular, the intensity transformation coefficients of Gaussian beams are analyzed in more detail.
