TL;DR: In this paper, it was shown that the set of first order systems that can be realized using axially symmetric thin lenses exhausts the entire SL(2, R) group; at most three lenses are needed to realize any element of this group.
Abstract: A first order optical system is investigated in full generality within the context of wave optics. The problem is reduced to a study of the ray transfer matrices. The simplest such systems correspond to axially symmetric propagation. Realization of such systems by centrally located lenses separated by finite distances is studied. It is shown that, contrary to the commonly held view, the set
of first order systems that can be realized using axially symmetric thin lenses exhausts the entire SL(2, R) group; at most three lenses are needed to realize any element of this group. In particular, the inverse of free propagation can be so realized. Among anisotropic systems it is again shown that every element of the lens group Sp(4, R) can be realized using a finite number of thin lenses.

TL;DR: In this paper, the scattering of electric polarized plane waves from an impedance half plane problem is examined by the method of modified theory of physical optics (MTPO), and two integrals, consisting of incident and reflected scattered fields, are obtained.
Abstract: The scattering of electric polarized plane waves from an impedance half plane problem is examined by the method of modified theory of physical optics (MTPO). Two integrals, consisting of incident and reflected scattered fields, are obtained. These integrals are evaluated asymptotically by the methods of stationary phase and edge point. The obtained scattered fields are compared with the exact solution numerically.

TL;DR: In this paper, a fast algorithm to calculate the radar cross section (RCS) of electrically large targets using a shooting-and-bouncing rays (SBR) method was presented.
Abstract: We present a fast algorithm to calculate the radar cross section (RCS) of electrically large targets using a shooting-and-bouncing rays (SBR) method. By applying multiresolution grid ray tubes, we accelerate the ray tracing in the SBR. The numerical results illustrate the accuracy and efficiency of our proposed algorithm. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 394–397, 2001.

TL;DR: In this paper, the scattering of light by media consisting of densely packed spherical particles was calculated by applying geometric optics and Monte Carlo simulation and found that when the packing density is increased, dark surfaces are clearly brightened, especially near grazing emergence and incidence.
Abstract: We have calculated the scattering of light by media consisting of densely packed spherical particles by applying geometric optics and Monte Carlo simulation. We found that when the packing density is increased, dark surfaces are clearly brightened, especially near grazing emergence and incidence. Also, the transmission through a finite layer is reduced with opaque particles but not with transparent ones. The results indicate that previous models that use low-density approximations (Lommel–Seeliger, Hapke, Lumme–Bowell, etc.) are not accurate for typical regoliths.
