Differential Kernels for Group Velocity [PDF]
Geophysical Journal International, 1976 Summary It is shown that the wavenumber dcrivative of the dispersion relation, dω(k)/dk, is a Frkchet differentiable gross Earth datum. The differential kernel functions are given explicitly as expressions quadratic in the normal mode eigenfknctions and their wavenumber derivatives.

Laser Ion Acceleration in a Near Critical Density Trap
Photonics, 2022 In order to accelerate ions by a laser, we go back to the original and the fundamental idea of how longitudinal field structure generation can be carried out in an ionized media and how particles may be trapped by the created wakefield.
