The properties of advanced composites rely on the quality of the fiber-matrix bonding. Service-induced damage results in deterioration of bonding quality, seriously compromising the load-bearing capacity of the structure. While traditional methods to assess bonding are destructive, herein a nondestructive methodology based on shear wave reflection is numerically investigated. Reflection relies ...

Mueller matrix differential decomposition is a novel method for analyzing the polarimetric properties of optical samples. It is performed through an eigenanalysis of the Mueller matrix and the subsequent decomposition of the corresponding differential Mueller matrix into the complete set of 16 differential matrices which characterize depolarizing anisotropic media. The method has been proposed ...

2014 The exact calculation of the reflection from single domain aligned samples of helicoidal liquid crystals (SmC* or cholesterics) is performed using the 4 x 4 matrix formulation of Maxwell equations in anisotropic media. We show that the expansion, approximation up to the 1st order of Berreman and Scheffer, is not adequate to describe the real situation, especially concerning the short wavel...

An approach to cascaded, uniform, lossless transmission-linenetworks by the transfer scattering matrix in the z-domain is presented.This approach can be applied to network problems treated in both the timeand the frequency domains and is well suited for a computer programming.It is shown that the reflection function and the transfer function areobtained by simple matrix mult...

We consider boundary scattering for a semi-infinite one-dimensional deformed Hubbard chain with boundary conditions of the same type as for the Y=0 giant graviton in the AdS/CFT correspondence. We show that the recently constructed quantum affine algebra of the deformed Hubbard chain has a coideal subalgebra which is consistent with the reflection (boundary YangBaxter) equation. We derive the c...

The effect of wall and indoor scatterers on the indoor multiple input multiple output (MIMO) communication system is investigated by using the hybrid technique of finite difference time domain (FDTD) method and method of moments (MoM). MIMO channel capacity with the wall reflection is investigated with consideration of the eigenvalue of channel covariance matrix, the received power and the effe...

Chrome-plated surfaces are perfectly specular, in which the diffuse reflection components are weak while the specular reflection components are so strong that their intensities saturate the CCD matrix and cause some surface features to be lost. This situation means that one image alone cannot show all of the surface features. To process specular reflection components, we proposed a novel multi-...

Based on rigorous mode expansion simulations, we consider the problem of guided light reflection at rectangular end facets of planar dielectric waveguides. Emphasis is on multimode structures with high refractive index contrast and on configurations that show a high reflectivity. Given the matrix of reflection coefficients for the guided fields, one can compute the maximum power reflectance for...
