Shielding prevents coupling of undesired radiated electromagnetic energy into equipment otherwise susceptible to it. In view of this, some studies on shielding effectiveness of different shields against angle of incidence with conductors and conductive polymers using plane-wave theory are carried out in this paper. The plane wave shielding effectiveness of new combination of these materials is ...

To date, devices exhibiting incidence-angle-dependent transmittance have been fabricated by imparting an angle to a bulk liquid crystal (LC) aligning the LC in vicinity of one substrate horizontally (with respect substrate) while another vertically. Another approach has control angles near substrates blending or layering horizontal and vertical alignment films. In this study, we controlling pre...

We experimentally studied the transmission response of a one-dimensional rectangle-prism-shaped metamaterial slab for oblique incidence angles. The electrical size of the split-ring resonators was 1 order of magnitude smaller than the operation wavelength ~8.5 cm. We demonstrated that the left-handed transmission peak preserved up to an angle of incidence 45 degrees . The angular measurements w...

objective(s):glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. glutathione s-transferases (gsts) are members of multigenic family, which have important role in cells as an antioxidant. in the present study, we examined the polymorphism of gstt1 and gstm1 deletion genotypes (t0m1, t1m0, and t0m0) in 100 glaucoma patients (41with pr...

RESUME Wide swath imagery of the ENVISAT Advanced Synthetic Aperture Radar (ASAR) may be used to study and map biophysical parameters of the Siberian forest. Within this study multi incidence-angle capacities of the ASAR Wide Swath (WS) mode for deriving forest types and biomass parameters are assessed. For this purpose a processing chain was set up to manage orthorectify, calibrate and analyse...

The backscattered field of an illuminated sphere with diameter ∅ = 30.5 cm above a perfect conducting plate is measured in an anechoic chamber at different heights for a varying incidence angle φ in the range 5◦ to 75◦. A high frequency field λ ∅ is transmitted, so that two significant transitions from lit to shadow regions are given over the entire incidence angle range for the considered ray ...

A detailed study of the stability of CsI and KBr photocathodes under UV irradiation is presented. UV quantum efficiency degradation was found to be more pronounced at lower illumination intensity for the same accumulated dose and illumination wavelength. For an equal number of extracted photoelectrons in-band UV exposure led to a larger sensitivity decay as compared to out-of-band illumination....

Three image-based methods for correcting the effect of changes in incidence angle on backscatter data are proposed and evaluated for AirSAR data of a coastal tropical savanna landscape in Australia's Northern Territory. These correction methods require little field knowledge and do not assume a linear relationship between sAR backscatter and incidence angle. The correction methods are applied t...

We have designed a tunable, oblique-incidence resonant grating filter that covers the C band as an add-drop device for incident TE-polarized light. We tune the filter by tilting a microelectromechanical systems platform onto which the filter is attached. The fabrication tolerances as well as the role of finite incident-beam size and limited device size were addressed. The maximum achievable eff...

An investigation of reflection and transmission phenomena of plane longitudinal wave from a plane interface between two distinct micropolar porous elastic solid half-spaces in welded contact has been made. Using the method of potentials, the appropriate boundary conditions at the interface are solved to obtain the amplitudes of various reflected and transmitted waves. It has been noticed that t...
