In a previous article the Einstein-Maxwell field equations for non-null electromagnetic fields were studied under the conditions that the null tetrad is parallel-propagated along both principal null congruences. A solution with twist and shear, but no expansion, was found and was conjectured to be the only expansion-free by: 9.

The Einstein-Maxwell field equations for non-null electromagnetic fields are studied under the conditions that the null tetrad is parallelly propagated along both principal null congruences.

It is shown that the resulting spacetime solutions are necessarily algebraically general. The Einstein-Maxwell field equations for non-null electromagnetic fields are studied under the conditions that the null tetrad is parallelly propagated along both principal null congruences.

A class of algebraically special non-null electrovac solutions is presented, in which the repeated principal null congruence is shear free, twist free, and geodesic, and is not aligned with a principal null direction of the electromagnetic field.

tensor is algebraically special, but the reverse no longer holds. A key property in this respect is the Kundt-Trümper theorem26, which says that for an algebraically special aligned non-null Einstein-Maxwell space-time (with a possible non-0 cosmological constant and with kthe PND of F coinciding with a multiple Weyl-PND) one necessarily has.

We present a class of pairs of non-trivially conformally related solutions of Einstein-Maxwell equations that are not pp-waves. To our knowledge, this is the first such case and thus an extension.
