We extend the rotation measure work of Burn (1966) to the cases of limited sampling of λ2 space and non-constant emission spectra. We introduce the rotation measure transfer function (RMTF), which is an excellent predictor of nπ ambiguity problems with the λ coverage. Rotation measure synthesis can be implemented very efficiently on modern computers. Because the analysis is easily applied to wi...

FeCo nanoparticles synthesized on sepiolite microparticles were used for the preparation of nanocomposites by melt compounding with polystyrene. Both, the sepiolite fibers and the nanoparticles were free of agglomeration, which allowed preparing nanocomposites with a homogeneous dispersion of the second phases, avoiding the usual agglomeration of the nanoparticles and minimizing light scatterin...

This document explores some of the issues involved in searching for transients, pulsars, and ETI signals with a widefield instrument. We assume also that steady sources are surveyed at the same time, including spectral lines and continuum radiation from galaxies and AGNs. We present a survey metric that quantifies survey completeness and incorporates time-variable sources with arbitrary duratio...

We present multi-frequency polarization observations of the diffuse radio synchrotron background modulated by Faraday rotation. No total intensity is observed, indicating that total intensity does not vary on scales below approximately a degree. However, polarized intensity and polarization angle show abundant smallscale structure due to Faraday rotation in the warm ionized disk on small scales...

This document explores some of the issues involved in searching for transients, pulsars, and ETI signals with the assumption that steady sources are surveyed at the same time, including spectral lines and continuum from galaxies and AGNs. We present a survey metric that quantifies survey completeness and incorporates time-variable sources with arbitrary durations and event rates. We discuss the...

We present a new approach in modelling the polarized Galactic synchrotron emission in the microwave range (20-100 GHz), where this radiation is expected to play the leading role in contaminating the Cosmic Microwave Background (CMB) data. Our method is based on real surveys and aims at providing the real spatial distributions of both polarized intensity and polarization angles. Its main feature...

It is clear there is a dire need of both soil moisture measurements and sea surface salinity retrievals as they are key parameters of the Earth system. To access them in a global and reliable fashion it seems that – even if complemented by other measurements, L-band radiometry is currently the best choice. The advantages are linked to an optimal trade off between high sensitivity to soil moistu...

Ionospheric propagation effects have a significant impact on the signal properties of SAR observations, especially at low operation frequencies. Dispersion, group delay, Faraday Rotation (FR), and phase shifts are all a function of the socalled Total Electron Content (TEC), the operating frequency and the system bandwidth. In order to choose the right acquisition time with lower ionospheric imp...

Experimental and theoretical studies of light coupling to various magnetic nanostructured media and nanocomposites are briefly reported. Enhancement of the magneto-optical response is shown to occur when the constitutive materials of photonic crystals are magnetic. Transmission and reflection types of 1D magnetophotonic crystals (MPCs) have been studied. New possibility to enhance the magneto-o...

The Southern Galactic Plane Survey (SGPS) is an H I and 1.4-GHz continuum survey of the 4th quadrant of the Galaxy at arcmin resolution. We present here results on linearly polarized continuum emission from an initial 28-square-degree Test Region for the SGPS, consisting of 190 mosaiced pointings of the Australia Telescope Compact Array, and covering the range 325.5< l < 332.5, −0.5< b< +3.5.
