  We study plane-fronted electrovacuum waves in metric-affine gravity theories
(MAG) with cosmological constant. Their field strengths are, on the
gravitational side, curvature $R_{\alpha}{}^{\beta}$, nonmetricity
$Q_{\alpha\beta}$, torsion $T^{\alpha}$ and, on the matter side, the
electromagnetic field strength $F$. Our starting point is the work by
Ozsv\'ath, Robinson, and R\'ozga on type N gravitational fields in general
relativity as coupled to null electromagnetic fields.
