Comparison of surface scattering between identical, randomly rough metal and dielectric diffusers.

چکیده
A method of replicating randomly rough surfaces fabricated in photoresist has been developed, enabling comparisons of the scattered light to be made between identical diffusers made from different materials. Experimental measurements on one-dimensional metal (gold) and dielectric surfaces are presented, and some initial comparisons with numerical calculations are made.

Study on the Light Scattering from Random Rough Surfaces by Kirrhoff Approximation
In order to study the space distribution characteristics of light scattering from random rough surfaces, the linear filtering method is used to generate a series of Gaussian randomly rough surfaces, and the Kirchhoff Approximation is used to calculate the scattered light intensity distribution from random metal and dielectric rough surfaces. The three characteristics of the scattered light inte...
متن کاملA Numerical Simulation of Scattering from One-Dimensional Inhomogeneous Dielectric Random Surfaces - Geoscience and Remote Sensing, IEEE Transactions on
In this paper, an efficient numerical solution for the scattering problem of inhomogeneous dielectric rough surfaces is presented. The inhomogeneous dielectric random surface represents a bare soil surface and is considered to be comprised of a large number of randomly positioned dielectric humps of different sizes, shapes, and dielectric constants above an impedance surface. Clods with nonunif...

متن کاملElectromagnetic Scattering From a Dielectric Cylinder Buried Beneath a Slightly Rough Surface
An analytical solution is presented for the electromagnetic scattering from a dielectric circular cylinder embedded in a dielectric half-space with a slightly rough interface. The solution utilizes the spectral (plane-wave) representation of the fields and accounts for all the multiple interactions between the rough interface and the buried cylinder. First-order coefficients from the small pert...
