density ductnumerical simulations[1] This paper presents results from a study of propagation of very-low-frequency electromagnetic waves (whistlers) inside high-density ducts (HDDs) in the Earth's magnetosphere. The main hypothesis investigated in this study is that whistlers can propagate without ...
The influence of a point spectrum on large sample statistics of the autoregressive (AR) spectral estimator is addressed. In particular, the asymptotic distributions of the AR coefficients, the innovations variance, and the spectral density estimator of a finite-order AR(p) model to a mixed spectru...
It is shown that the spectral density has a form of wide feature at thr frequency scale of the plasmon frequency, without the presence of quasi-particle delta-peaks. The relevance of this result with respect to experimental findings and to the theory of Luttinger liquids is discussed....
A study of the optical properties, the spectral response, and lifetime of the endogeneous fluorescence on brain tissue, will allow an understanding of the evolution of the hyperstructure, the metabolic process and environment transitionning from a healthy region to a tumoral region. In this paper...
athe optical properties of filters may be divided into intrgral and spectral characeristics. the spectral characteristics again fall into several subcategories: 1 sharp-cutting(high-pass or low-pass) 1 band-pass(wide or narrow) 3 compensating 4 neutral density . in integral terms the performace...
Here, we bring out the studies made on the production and optical characterization of certain terbium glasses in the following composition: 44.5B 2 O 3 +44.5P 2 O 5 +10R 2 SO 4 (where R=Li, Na, K). From the glass density ( d ) and refractive index ( n f , n d , n c ) ...
We have used infrared spectroscopic ellipsometry to interrogate the dielectric response of a series of Hg 1 x Cd x Se samples in a spectral range between 2000 and 40000nm. Using a standard inversion technique, the experimental data obtained at multiple angles of incidence were modeled to deduce ...
