WebJul 4, 2015 · Metrics. The polarization status of in- and out-of-plane scattered light from macroscopically rough surfaces was measured and expressed in a scattering coordinate system. In this coordinate system, the direction of the scattered light was decided by the transverse and longitudinal scattering angles, both of which are defined by using the ... WebIn rough surface scattering, the surface enters in the boundary conditions (see equations (2.2.1)-(2.2.4)), which have to be also supplied at infinity. If we consider time-harmonic variation of the electromagnetic field, the instantaneous field vectors can be related to their complex forms. Thus the Maxwell s equations can be written
