Abstract

We study plane-fronted electrovacuum waves in metric-affine gravity theories with a cosmological constant. Their field strengths are, on the gravitational side, curvature $R_{α}^{β},$ nonmetricity $Q_{α β},$ torsion $T^{α}$ and, on the matter side, the electromagnetic field strength F. Our starting point is the work by Ozsváth, Robinson, and Rózga on type N gravitational fields in general relativity as coupled to null electromagnetic fields.
