Measurement of optical rotation in RbTiOAsO4 (RTA) with the tilter method resulted in an optical rotation of r12 1⁄4 þ17ð3Þ /mm at a wavelength of 670 nm, when a (100) sample was tilted about [001]. A tilt about [010] showed no rotation, as expected from the directional dependence of optical rotation calculated from the tensor in point group mm2. The absolute Miller-indices of the samples were ...

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...

Circular dichroism (CD) data are reported of a series of 9,10stereoisomeric steroidal 5,7-dienes. In general the effects in the longest wavelength transition (270-280 nm) are large (Mm" 10---30) and consignate with respect to the diene helicity rule. The magnitude of the CD appears to vary markedly with the substituent at C-3 and at C-17, and with solvent. In the case of the 9a,10p-H dienes, va...

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...

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...

The standard scalar paraxial parabolic (Fock–Leontovich) propagation equation is generalized to include allorder nonparaxial corrections in the significant case of a tensorial refractive-index perturbation on a homogeneous isotropic background. In the resultant equation, each higher-order nonparaxial term (associated with diffraction in homogeneous space and scaling as the ratio between beam wa...

A new polarimetric calibration method using polarization orientation angle shifts at built-up areas and standard calibrators is studied. Calibration matrices were derived from datasets of the Gifu and the JAXA Tomakomai calibration sites, which are almost the same as those by JAXA. Faraday rotation angels in observed datasets can be estimated. Two estimated Faraday rotation angles were reasonable.

We study optical activity induced by curvature. The optical activity model we present has two phenomenological gyration parameters, within which we analyze three model cases, namely, an exactly integrable model, the Landau-Lifshitz model and the Fedorov model, these latter two are solved in the short wavelength approximation. The model background is a gravitational pp-wave. The solutions show t...
