Implicit, perturbative algorithms [B. I. Cohen, A. M. Dimits, J. J. St
imson, and D. C. Barnes, Phys. Rev. E 53, 2708 (1996)] are extended to
address electromagnetic particle simulation of drift-wave instabiliti
es in electron and ion plasmas with a strong applied magnetic field. T
he algorithms use gyrokinetic ions and drift-kinetic electrons with a
realistic mass ratio. Implicit moment and direct implicit solutions of
the coupled Maxwell and plasma dynamical equations are demonstrated.
Aspects of the numerical dispersion properties are confirmed in test s
imulations. Applications to ion-temperature-gradient and collisionless
drift instabilities in a two-dimensional slab with magnetic shear are
presented that illustrate the efficacy of the algorithms and the elec
tromagnetic effects.
