Based on theoretical investigation it is necessary to define the geometry of the light guide, it is known that the starting point has to be such, that the incidence light from the source would have incidence angle inside the light guide equal to critical angle for total internal reflection to take place and for the system to be in equilibrium.
The optical simulation setup included the two RTP arrays (each placed on 10[degrees] inclined slopes), a 1 W light source casting rays at 0[degrees] incidence angle with respect to the retroreflective array, 5 * [10.
Grazing incidence X-ray diffraction (GI-XRD) measurements employing Cu-K[alpha] radiation were done at three grazing incidence angles of 0.
2%), the ability to use an adequate incidence angle reduces the possibility of puncturing the carotid artery; moreover, real time visualization prevents a too deep advancement of the needle, thus lowering the possibility of a pneumothorax.
Those bright white regions on front slopes are with extremely high backscattering intensity caused by small local incidence angle or foreshortening and layover.
For a given value of the incidence angle, the critical frequencies satisfy
To this end, we used multibeam echosounder data to generate metrics that describe the seafloor: backscatter strength at normal and oblique incidence angles, the variation of the angle-dependent backscatter strength within 10[degrees] of normal incidence, the scintillation of the acoustic intensity scattered from the seafloor, and the seafloor rugosity.
high ACRs occur in the range of wind incidence angle from 90[degrees] to 135[degrees], while low values are found from 157.
With a 45[degrees] incidence angle, ExciLife-193 coatings are guaranteed to provide greater than 97% reflectance at 193 nm, certified in PI/Acton's in-house metrology laboratory.
