In this review we examine the amplitude intensity associated to tensorial andnon-tensorial polarization modes generated by binary systems at their inspiralstage, within the alternative theories of gravity of Brans Dicke, Rosen, andLightman Lee. This study is performed without making an explicit use of theTransverse Traceless gauge of the General Relativity approach, and at theNewtonian limit. Consequently such additional polarization modes appear(non-tensorial) due to additional degrees of freedom in modified theories ofgravitation. We model and compare the different polarization modes and strainsignals for each scheme varying the sky location. Our analysis allows us toidentify the locations where these modes are more intense, and, thereforesusceptible to being identified for the future interferometer detector network.This gives rise to a framework in which the amplitude and the intensity of allpolarization modes of general relativity and alternative hypotheses can becompared.
