The transmission spectra of TE and TM polarized waves for the ternary structure at various angles of incidence and for [gamma] = 0.2 x [10.sup.-3] GHz are shown in Figures 3(a) and 3(b), respectively.
The error introduced by this assumption is particularly severe for shallow gratings and for large angles of incidence. RCWA was used to determine the exact grating period adjustment as a function of angle of incidence.
However the lift of the isolated wing exceeds that of the plane for the bigger angles of incidence. This is dues with the fact that the Reynolds number of the tests of the isolated wing is much higher than that of the plane tested numerically which leads to higher maximum Cz for the isolated wing.
ANGLES OF INCIDENCE - Finally, when selecting a nozzle, the operator should understand the angles of the nozzle's jets and how they affect the tool's ability to do the work required.
They looked at levels and angles of incidence of both ultraviolet A and B radiation at various latitudes.
Both ultra-broadband mirrors operate within 0- to 50-degree angles of incidence. The high-energy Nd:YAG laser mirrors with HE.
A measure that rates the overall sound-absorption performance of a material when used in an enclosed architectural space, such as an office, where sound is being reflected at many angles of incidence. A material with a NRC of less than 0.50 is a poor absorber; a NRC of greater than 0.80 is a very good absorber.
Measurements with a rotatable sample holder were particularly useful since they served the purpose of validating the measurements obtained with the IS and also gave some information on the transmittance at grazing angles of incidence.
In chapter four Saiber reaches the conclusion that the De gli eroici furori is a contamination of vision and desire, and she sheds light on the "angles of approach, angles of incidence, symmetry, and the prismatic, fragmented journey one must travel to gain knowledge of an ultimately elusive goal" (114).
The geometry of the system is what differentiates TXRF from XRE XRF systems use large angles of incidence, but TXRF systems have the X-ray source aligned so that the X-rays are incident on the surface of the sample at a very small angle, generally less than one degree.
However, since the 1980s, with the introduction of high sensitivity modern Fourier transform infrared spectrometers (FTIR), and in particular FTIR microscope systems, mid-infrared reflection-absorption spectroscopy at near normal angles of incidence has become quite a commonly used direct sampling technique for fingerprinting coating layers on reflective substrates.
The modified theory presented in this paper is valid for normally incident light but can easily be adapted for oblique angles of incidence. As will be shown, it becomes indistinguishable from the usual Fresnel approximation in the mid zone z [much greater than] [lambda], and here the latter can be used with confidence.
A volume hologram medium comprises a reflection hologram in which a stereoscopic image of a three-dimensional object and an image of a plane pattern of a mask plate are recorded by interference of the same reference light beams having the same angle of incidence and the same wavelength with object light beams having mutually different angles of incidence. The stereoscopic image of the three-dimensional object is reconstructed in the form of diffracted light in a single colour and in angle relations close to recording conditions, and the image of a plane pattern of the mask plate is reconstructed as diffracted light at various angles of incidence of white illumination light and in different colours depending on those angles of incidence.
An incidence angle of -30[degrees] was chosen as a compromise between the loss of contrast (at lower angles of incidence) and the loss of light from the bottom of the scratch (at higher angles of incidence).
The small standard deviations indicate that flow in the boundary layer adjacent to the flux sensor has a relatively low turbulence intensity at these angles of incidence. In contrast, fluxes at negative angles of incidence (with the sensor on the leeward face of the plate) are high and associated with relatively high turbulence-intensities (evidenced by the large standard deviation among cycles).
