This paper gives an overview of activities and results from the Swedish part of the international calibration and validation efforts for ALOS PALSAR. Four large trihedral corner reflectors were deployed and the measured co-polar responses showed that the PALSAR system performed well and was stable over time. The cross-talk level was found to be lower than – 34.5 dB. Two different methods for es...

Radio observations of large-scale magnetic fields in spiral galaxies suggest that these fields show in many cases a dominating S0 symmetry, i.e. even symmetry to the central plane and axisymmetry with respect to the rotational axis. In addition, detailed evaluation of Faraday rotation measures in five nearby galaxies reveals that in four cases the magnetic field lines are directed toward the ce...

We constructed an apparatus to measure the wavelength dispersion of the Faraday rotation in the visible region, and determined the Verdet constants of diamagnetic organic liquids, including aliphatic compounds, benzene derivatives, and naphthalene derivatives. These three groups were easily distinguished by the magnitudes of their Verdet constants. Based on the theory developed by Serber, we ...

We demonstrate that giant Faraday rotation in graphene in the terahertz range due to the cyclotron resonance is further increased by constructive Fabry-Perot interference in the supporting substrate. Simultaneously, an enhanced total transmission is achieved, making this effect doubly advantageous for graphene-based magneto-optical applications. As an example, we present far-infrared spectra of...

Faraday rotation is a valuable diagnostic tool for investigating laboratory and astrophysical plasmas, but it has almost exclusively been treated in the collisionless limit (despite non-negligible role of Coulomb collisions many plasmas). Here, we show that can occur collisional plasmas usual effect curiously altered by collisions. Namely, an initially linearly polarized light wave—propagating ...
