- W2121069341 abstract "We start with the linearized plasma equations containing an isotropic pressure term, plus extra source terms ${mathrm{J}}^{s}$ and ${ensuremath{rho}}^{s}$ in the Maxwell equations. The fields of (${mathrm{J}}^{s}, {ensuremath{rho}}^{s}$) can be decomposed into two modes. The electromagnetic (EM) mode has all the magnetic field and no charge accumulation; it is the ordinary EM field of (${mathrm{J}}^{s}, {ensuremath{rho}}^{s}$) in a dispersive medium of relative dielectric constant ${ensuremath{epsilon}}_{r}=1ensuremath{-}{(frac{{ensuremath{omega}}_{p}}{ensuremath{omega}})}^{2}$. The plasma (P) mode has all the charge accumulation and no magnetic field; at great distances from the source, it becomes a longitudinal (radial) plasma wave with the usual dispersion relation for plane plasma waves. Various potentials for the EM and P modes are given by the inhomogeneous Klein-Gordon equation. The fields of a uniformly moving charged particle are found by a Lorentz transformation. When $(frac{u}{{v}_{0}})<1$ ($u=mathrm{particle}mathrm{velocity}$, ${v}_{0}=mathrm{rms}mathrm{thermal}mathrm{velocity}$), the EM and P fields are exponentially screened outside oblate spheroids foreshortened in the direction of motion. When $(frac{u}{{v}_{0}})>1$, the $P$ field exists only within the Mach (ifmmode check{C}else v{C}fi{}erenkov) cone trailing the particle. The frequency and angular spectra of the ifmmode check{C}else v{C}fi{}erenkov radiation are found, and the total radiated energy is found by assuming an arbitrary high-frequency cutoff due to Landau damping. The expression for total radiated energy agrees with that given by Pines and Bohm, except for the logarithmic terms." @default.
