Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A detailed account of a formal mathematical description of the interaction of relativistic charged particle beams with electromagnetic waves, within the frame of classical electrodynamics, is presented. The standard system of eight equations (Maxwell and Lorentz gauge conditions and fluid dynamics) in the four-vector potential A and the four-vector current density j is reduced, after linearization, to a canonical system of four coupled partial differential equations in the electromagnetic field perturbation A. Both electromagnetic and dynamical quantities are treated as fields, according to the Eulerian formalism. This new system is very general, and different beam-wave interactions are characterized by different fluid equilibria and boundary conditions for A and its derivatives. Finally, the equations are used, as an example, to study the dispersive characteristics of space-charge waves propagating in a cylindrical waveguide, along a relativistic electron beam confined by an axial magnetic field. The problem is treated in a fully relativistic way, for arbitrary values of the axial guide field and any degree of azimuthal symmetry. © 1990 The American Physical Society.
