Two-element free-electron lasers [PDF]
Optics Letters, 1980 The interaction between the electrons and the radiation in a free-electron laser leads to a shift and a spread of the electron velocity distribution. The electron dynamics of a two-element system are studied in the small signal region. It is found that the efficiency and gain can be increased through introduction of an adjustable drift distance between

Application of Element Free Galerkin Method to Navier-Stokes Equation
Journal of Algorithms & Computational Technology, 2009 Element Free Galerkin Method (EFGM) is one of the effective computational methods in the mesh-free method, which does not require time-consuming mesh generation. This means that EFGM can be available for irregular nodes in the computational domain.
