At 150 K, the title compound, C(9)H(11)NO(4)S, crystallizes in the orthorhombic form as a zwitterion and has a low gauche conformation [chi = -46.23 (16) degrees] for an acyclic cysteine derivative. A difference in bond length is observed for the alkyl C-S bond [1.8299 (15) A] and the aryl C-S bond [1.7760 (15) A]. The -NH(3)(+) group is involved in four hydrogen bonds, two of which are intermo...

We describe a method of selective generation and study of polarization moments of up to the highest-rank kappa=2F possible for a quantum state with total angular momentum F. The technique is based on nonlinear magneto-optical rotation with frequency-modulated light. Various polarization moments are distinguished by the periodicity of light-polarization rotation induced by the atoms during Larmo...

We introduce a new perspective on magnetoplasmonics in nickel nanoferromagnets by exploiting the phase tunability of the optical polarizability due to localized surface plasmons and simultaneous magneto-optical activity. We demonstrate how the concerted action of nanoplasmonics and magnetization can manipulate the sign of rotation of the reflected light's polarization (i.e., to produce Kerr rot...

A pair of mutually twisted metallic cross-wires can produce giant optical activity. When this single chiral layer is stacked layer by layer in order to build a thick chiral metamaterial, strong coupling effects are found between the two adjacent chiral layers. We studied these coupling effects numerically and experimentally. The results show that the existing coupling between chiral layers can ...

We analyse the optical activity in twisted dimers, the meta-atoms of a chiral metamaterial, by introducing a simple yet accurate model for the coupling between them. The near-field interaction coefficients are derived from a Lagrangian model and include the effects of retardation, whereas the far-field radiation is based on a multipole expansion. We show that the optimum twist angle varies with...

L-Band SAR, like that on the JAXA’s ALOS PALSAR instrument, is much more susceptible to ionospheric effects than other space based SAR missions, mainly operating in C-band or X-Band. While single-band attenuation of instruments such as the single-polarization JERS-1 SAR instrument certainly occurred, it was rarely noted. With the advent of fulland dual-polarization (full-pol and dual-pol) instr...

Following the recent observation of a large second-harmonic intensity difference from a monolayer of chiral molecules with left and right circularly polarized light, the scattering theory is generalized and extended to predict linear and circular intensity differences for the more versatile sum-frequency spectroscopy. Estimates indicate that intensity differences should be detectable for a typi...

We propose a model to describe a gas of pyramidal molecules interacting via dipole-dipole interactions. A cooperative effect induced by the interaction modifies the tunneling properties between the classical equilibrium configurations of the single molecule. The model suggests that, for sufficiently high gas density, the molecules become localized in these classical configurations. On this basi...

The paper presents the ionospheric effect on the power transmitted by satellite solar power station. Consequently, the Faraday rotation and losses due to ionospheric layer are calculated at 2.45GHz frequency. It is observed that the fluctuation in the Faraday rotation in day time is found to be the maximum as compared to the night hours and. Loss due to depolarization is found to have the maxim...
