Spherical detectors of gravitational waves
Resonant mass detectors of GWs of spherical shape constitute the fourth generation of such kind of antennae, and are scheduled to start operation in the near future. In this communication I present a general description of the fundamental principles underlying the physics of this kind of detector, as well as of the motion sensor set suitable to retrieve the information generated by the incidence of a GW on the antenna.

-  For example, its volume is 1.057 times that of its inscribed sphere, while the truncated icosahedron is 1.153 times less voluminous than its circumscribed sphere; this means sphericity is a factor of almost 3 better for our polyhedron.
-  The chosen distribution has the property that the frequency spacing between members of the associated multiplet is the most even compatible with the polyhedron face orientations.
