We propose a parallel factor (PARAFAC) analysis-based angle and polarization estimation algorithm for multiple coherent sources using a uniformly-spaced linear tripole sensor array. By forming a PARAFAC model using the spatial signature of the tripole array, the new algorithm requires neither spatial smoothing nor vector-field smoothing to decorrelate the signal coherency. We also establish tha...

This paper investigates the potential of joint use of multitemporal/polarization C-band SAR data for landcover classification. Multitemporal ENVISAT ASAR data with vv polarization and Radarsat-1 data with hh polarization are used in this study. The presented classification scheme consists of two analytical steps: one for feature extraction and the other for combination of features. A traditiona...

A systematic, statistical-mechanics-based analysis of the response of dielectric elastomers to coupled electromechanical loading is conducted, starting from the monomer level through the polymer chain and ending with closed-form expressions for the polarization and stress fields. It is found that the apparent response at the macrolevel is dictated by four microscopic parameters-the monomer type...

The FN method is used to establish numerical results basic to polarization studies in plane parallel atmospheres.

We present a partial-wave analysis of the polarization data for the reaction ~ p~ p → ppπ◦, based solely on the recent measurements at IUCF for this channel. The fit leads to a χ2 per degree of freedom of 1.7. Methods for an improved analysis are discussed. We compare the extracted values to those from a meson exchange model.

We numerically compute light and polarization curves of γ-ray burst afterglows for various configurations of the jet structure and for different dynamical evolutions. We consider a standard homogeneous jet and a structured jet with power-law wings. We show that the lightcurves from these two configurations are very similar to each other, and therefore only very high quality data could allow us ...

Micro-domes based on a combination of metallic and dielectric multilayer mirrors are studied using a fully vectorial numerical basis-expansion method that accurately accounts for the effects of an arbitrary Bragg stack and can efficiently cover a large range of dome shapes and sizes. Results are examined from three different viewpoints: (i) the ray-optics limit, (ii) the (semi-) confocal limit ...

An efficient and accurate method to the problem of planewave scattering from periodic arrays of two circular-cylinders per unit cell is presented. The scattered fields are calculated using the lattice sums characterizing a periodic arrangement of scatterers and the aggregate T -matrix for the isolated two-cylinders system in free space. The cylinders may be of dielectric, perfect conductor, or ...
