Sentence examples for near the reflection from inspiring English sources
This is especially noticeable for minimax phases such as SS waves with periods >20 s, when kernels become hyperbolic near the reflection point and appreciable sensitivity extends over thousands of km.
The difference in the group refractive index is significant when (X) approaches 1, i.e., near the reflection level.
An ingenious analytical method devised by Lundborg and Thide 1985 , 1986is used to calculate the variation of the characteristic-wave ( overrightarrow{E} ) near the reflection region, but only ordinary (O -mode waves are considered.
In this paper, we are interested in analyzing the variation of the ( overrightarrow{E} ) intensity near the reflection point caused by the initial vertical propagation of the HF radio waves in the ionosphere.
The variation of each component of the electric field and the total electric field intensity of the standing wave pattern under a specific density profile are calculated by means of a uniform approximation, which is applied throughout the region near the reflection point.
The Doppler sounding with continuous high-frequency (HF) radio waves detects the periodic fluctuation of phase length associated with the electron density perturbation near the reflection level (Yuen et al. 1969; Wolcott et al. 1984; Tanaka et al. 1984; Artru et al. 2004; Chum et al. 2012, 2016).
According to the Fresnel equations, when the light is at near-normal incidence, the reflection coefficient (reflectivity) from the interface between two contacting transparent materials is determined by their refractive indices n1 and n2: R = left( {frac{{n_{1} - n_{2} }}{{n_{1} + n_{2} }}} right)^{2}.
So the near infrared reflection features from the pupil were used in the image processing of the pupil movement data.
This is evident from the near smooth reflection pattern (weathered layer) and anomalous low resistivity values shown (Figs. 5, 6) whereas the other traverse set (Figs. 7, 8) displays subsurface layers with low hydraulic conductivity evident by planar reflections/moderate resistivity values (lateritic topsoil) and chaotic reflections/high resistivity values (basement).
In the GRUNDY 2003 experiment we combined wide-angle reflection refraction measurements with the near-vertical reflection seismics by the use of the constant geophone array with dense (100 m) receiver spacing occupying 50-km long profile.
(c) shows the simulated diffraction image near SiGe 004) reflection at the corresponding spot position shown in (a).
