A new free-wave experimental method for chiral media characterization is presented. The setup is based on a pair of dual horn antennas and a diplexer 90° phase shifter, which allows to produce both circularly and linearly polarized waves and to measure the co- and cross-polar components of the transmission and reflection coefficients of a chiral slab under normal illumination. Then, six experimental...
The atmospheric evolution on Mars is influenced by nonthermal loss processes of heavy atmospheric constituents. Since Mars does not have an appreciable intrinsic magnetic field at present and a comparatively small gravitational acceleration, all known atmospheric loss processes can be active and several important constituents are lost to space. The escape rates of atmospheric constituents including...
The paper deals with a coupled model of the upper atmosphere and ionosphere of Titan. The neutral atmosphere is described by a comprehensive photochemical model for 30 o solar zenith angle with molecular and turbulent diffusive transport taken into account. At the upper boundary (1430 km) escaping flux of light molecules is included in boundary conditions, while near the lower boundary (32...
