Study of Electromagnetic Scattering from Randomly Rough Ocean-Like Surfaces Using Integral-Equation-Based Numerical Technique
… is especially pronounced in the case of horizontal polarization and at low grazing angles. We show - both numerically and analytically - that the problem lies not with the particular numerical technique used (MOMI) but rather with how the MFIE is discretized. It is demonstrated that the …

Oceanic Rain Identification Using Multifractal Analysis Of Quikscat Sigma-0
… are flagged. The forward and aft views of the horizontal polarization σ0 are used for the extraction of textural information with the help of multi-fractals. A single negated multi-fractal exponent is computed to discriminate between wind and rain. Pixels with exponent value above a threshold …

An Ocean Surface Wind Vector Model Function For A Spaceborne Microwave Radiometer And Its Application
… (AMSR). AMSR observes the vertical and horizontal brightness temperature (TB) at six frequency bands between 6.9 GHz and 89.0 GHz. Although these measurements contain some wind direction information, the overlying atmospheric influence can easily obscure this signal and make wind …

YSCAT Backscatter Distributions
… found to adhere to a log-normal distribution for horizontal polarization and a generalized log-normal distribution for vertical polarization. If ρ(α|σ°) is assumed to be Rayleigh distributed, the instantaneous amplitude distribution ρ(α) is found to be the integral of a Rayleigh/generalized …

Systematic Investigation of Intermolecular Interactions in NEXAFS Spectroscopy
… C-H band (287-288 eV) changed when X-ray linear horizontal polarization was aligned along the principal axes (X,Y) of individual crystals. In addition to the observed linear dichroism, the room temperature NEXAFS spectra of orthorhombic alkanes becomes broader as the alkane chain length …

Cross-validation of spaceborne radar and ground polarimetric radar observations
… observations. The reflectivity factor (Zh) at horizontal polarization state and specific differential phase (Kdp) are determined along the PR beam from GR measurements, and a theoretical relationship is used to determine the expected specific attenuation along the space-earth path at Ku-band …

Wideband Terrestrial Path Loss Measurement Results For Characterization of Pico-cell Radio Links at 38 GHz and 60 GHz Bands of Frequencies
… locations, propagation frequencies and antenna polarizations. Path Loss Exponent values are also calculated and Rain Attenuation statistics are compared with popular rain models. Results from Frequency Diversity measurement campaigns are also presented.
