The phrase "at multiple reflections of" is correct and usable in written English.
It can be used in contexts discussing phenomena that involve repeated reflections, such as in optics or sound.
Example: "The experiment demonstrated the effects of light at multiple reflections of the surface, creating intricate patterns."
Alternatives: "during several reflections of" or "in various reflections of".
The echo sequence S1 at approximately 12 μs comes from multiple reflections of the excitation pulse on the sheet metal.
A person rides with a bicycle alongside the river Spree as it is photographed trough multiple reflections of windows at a courtyard of an parliament office building in Berlin Tuesday, Oct. 14, 2013.
Hence, as a result of multiple reflections at the boundaries of the layer, eight resulting waves with different directions of propagation and attenuation are developed.
In this work, the multiple reflections and uncertain reflectivity of water bottom are explicitly modeled.
The film behavior changes and a wavy pattern is seen below 1.8 eV, which can be due to the light scattering and multiple reflections at the interfaces of the film structure [18].
For the extraction of the complex refractive index, we used an iteration method based on the transfer matrix theory where the effects of multiple reflections at the interfaces between the slide, cartilage, and LDPE film are taken into account [ 19]. Figure 4 shows the refractive index images and absorption coefficient images of cartilage tissue at 0.4 and 0.8 THz.
The late reverberations are a result of multiple reflections, arriving at the receiver in random order, with successive reflections being damped based on the arrival time, that is, reflection amplitude is damped to a greater degree if they arrive (at the receiver) later in time.
However, as the figure shows, returns from ranges 1, 2, and 3 in the E region appear at lower ranges at later times as a consequence of multiple reflections from the E region.
