  These notes address the planar gravitational wave solutions of general
relativity in empty space-time, and analyze the motion of test particles in the
gravitational wave field. Next we consider related solutions of the Einstein
equations for the gravitational field accompanied by long-range wave fields of
scalar, spinor and vector type, corresponding to particles of spin s=(0,1/2,1).
The motion of test masses in the combined gravitational and scalar, spinor or
vector wave fields is discussed.
