The error introduced by this assumption is particularly severe for shallow gratings and for large angles of incidence.
However the lift of the isolated wing exceeds that of the plane for the bigger angles of incidence.
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.
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.
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.
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).
The infrared light used is unaffected by ambient light conditions and enables readings to be taken at greater distances and angles of incidence than when using many other optical tachometers.
Back in 1886, Dessau (1886) reported on depositing thin films using evaporation onto substrates at various angles of incidence.
A useful feature of the single solid wall is the ability to have fairly low reflections (below -10 dBi) in both polarizations up to very high angles of incidence (over 80 [Degrees]).
6 were tested for reflectivity at several angles of incidence.
The design called for a material that would be a safety railing for a second-level, exterior mezzanine while acting as an effective sun screen to combat the sun's rays at high angles of incidence for lower level classrooms.
