an′gle of in′cidence


n.
1. Also called incidence. the angle that a ray, as of light, makes with a normal to a surface at the point where the ray meets the surface.

The elastic impedance for a given angle of incidence [theta], the reflection coefficient R as a function of [theta] is given as,
To study the behaviour of the designed FSS in terms of the angle of incidence, the FSS has been simulated rotating it around its F-axis, from [phi] = 0[degrees] to [phi] = 45[degrees] as depicted in Figure 8(a).
The current study shows that pressure induced on the model building is significantly affected by the model geometry, configuration, aspect ratios, and angle of incidence. The significant outcomes of the present study are summarized as follows:
In summary, we evaluated the electronic transmission through single and double barriers in silicene as a function of the angle of incidence [theta], the electron energy E, and the strength of the field [E.sub.z] and obtained a spin-resolved transmission, especially for near-normal incidence, and a conductance qualitatively different in some ranges of E than that in graphene.
In contrary to the tip-source case, we have additional free parameter in this study, namely, the angle of incidence. Its influence in the case of gold substrate and wavelength 632.8 nm is shown in Figure 2.
Moreover, incidence angle modifier (IAM) is determined as a ratio of instantaneous thermal efficiency at an angle of incidence to peak thermal efficiency as [24, 25]
The transmission and reflection spectra for effective model and the real structure at the angle of incidence 30 and 60 degrees are shown in Figure 8.
It is further observed from Figure 2 that the variation in the amplitude levels (i.e., the resonance bandwidth) in TM mode increases with increase in the angle of incidence, whereas in TE mode, it is falling rapidly as the angle of incidence increases.
Figure 9 shows efficiency of [+ or -] 1st diffraction orders in TE polarization and that of the sum of the two orders as a function of the angle of incidence in the case of a grating period of 600 nm.
The oblong appearance of the flooded circular voids is due to the oblique angle of incidence of the THz beam in the Brewster's angle imaging configuration.
"Present-day light detectors suffer from severe reflection losses as currently used anti-reflection coatings are limited to specific wavelengths and a fixed angle of incidence. Our detector captures light without such limitations by taking advantage of a nanostructured surface.
Optical simulations were conducted to determine the RRE of the three RTPs as the angle of incidence was changed from 0[degrees] to 45[degrees] in 5[degrees] increments.
