abstract = "There is a host of alternative theories of gravitation in the
literature, among them the f(R, T) and f(R, T-phi) theories
recently elaborated by Harko et al. In these theories, R, T and
T-phi are respectively the Ricci scalar and the traces of the
energy-momentum tensors of matter and of a scalar field. There is
already in the literature a series of studies of different forms
of the f(R, T) and f(R, T-phi) functions as well as their
cosmological consequences. However, there have been no studies so
far related to gravitational waves. Here we consider such an
issue, in particular, studying the putative extra polarization
modes that can appear in the scope of such theories. Different
functional forms of f(R, T-phi) are considered and the
gravitational waveforms are found for the extra polarization modes
in the cases in which they are present.",
