expansion-free electromagnetic solutions of Kerr-Schild class
(AIP Publishing, 1974-07)
Starting with the general Kerr_Schild form of the metric tensor,d s2=_+l_l (where l is null and _ is flat space_time), a study is made for those solutions of the Einstein_Maxwell equations in which l is geodesic, shear_free, ...
power statistics for wave propagation in one-dimension and comparison with radiative transport-theory. II.
(AIP Publishing, 1974-12)
We consider the one_dimensional problem of a slab having a random index of refraction and illuminated from within by a point source. We compute the expected value and the fluctuations of both the total power and power flux. ...
