R. Zwiggelaar et Mgf. Wilson, SPECTRAL CHANGES IN INHOMOGENEOUS-MEDIA - A QUASI-OPTICAL APPROACH, International journal of infrared and millimeter waves, 14(10), 1993, pp. 2253-2259
Spectral changes in inhomogeneous media depending on the spatial coher
ence of the source can be described by a quasi-optical approach. Assum
ing a Gaussian-Schell model source the spectral changes are described
by using a Gaussian beam and ABCD matrices for the propagation in the
medium.
