The model advances the perturbed electromagnetic fields $E$ and $B$ directly, rather than the scalar and vector potentials. The parallel electric field $E_\\parallel$ is obtained from Ohm's law. The perpendicular electric field $E_\\perp$ is computed from Amp\\`ere's law by extracting the $E_\\perp$-dependent component of the drift-kinetic electron current.
