We have studied a (1+2)-dimensional Lorentz-violating model which is obtainedfrom the dimensional reduction of the nonbirefringent sector of the CPT-evenelectrodynamics of the standard model extension (SME). The planar theorycontains a gauge sector and a scalar sector which are linearly coupled by meansof a Lorentz-invariance violating (LIV) vector, $S^{\mu}$, while the kineticterms of both sectors are affected by the components of a Lorentz-violatingsymmetric tensor, $\kappa^{\mu\nu}$. The energy-momentum tensor reveals thatboth sectors present energy stability for sufficiently small values of theLorentz-violating parameters. The full dispersion relation equations areexactly determined and analyzed for some special configurations of the LIVbackgrounds, showing that the planar model is entirely nonbirefringent at anyorder in the LIV parameters. At first order, the gauge and scalar sectors aredescribed by the same dispersion relations. Finally, the equations of motionhave been solved in the stationary regime and at first order in the LIVparameters. It is observed that the Lorentz-violating parameters do not alterthe asymptotical behavior of the electric and magnetic fields but induce anangular dependence which is not present in Maxwell's planar theory.
