Generalized Reflection Coefficients [PDF]
Communications in Mathematical Physics, 2015 I consider general reflection coefficients for arbitrary one-dimensional whole line differential or difference operators of order $2$. These reflection coefficients are semicontinuous functions of the operator: their absolute value can only go down when limits are taken.

Microwave Radar Sensing of Sea Waves: An Effective Reflection Coefficient
Russian Journal of Earth Sciences, 2023 At the small incidence angles, the dominant backscattering mechanism for sea waves is the quasi-specular backscattering mechanism. The power of the reflected signal depends on the distribution function of the slopes of large-scale waves (in comparison ...

Theoretical and Experimental Studies of Acoustic Reflection of Bubbly Liquid in Multilayer Media
Applied Sciences, 2022 Bubbly liquids are widely present in the natural environment and industrial fields, such as seawater near the ocean bottom, the multiphase flow in petroleum reservoirs, and the blood with bubbles resulting in decompression sickness.

Negative reflection coefficients [PDF]
Transactions of the Faraday Society, 1965 The reflection coefficient of porous Vycor glass towards aqueous solutions of polyethylene glycol, measured by ultrafiltration, has negative values at lower polymer concentrations. This is in qualitative agreement with the abnormally low and negative values of the apparent osmotic pressure found by Elias for such systems.

Wave reflection in semiconductor nanostructures
Theoretical and Applied Mechanics Letters, 2018 : Based on nonlocal thermoelastic theory, this article studies the reflection of waves in nanometer semi-conductor media. Firstly, the governing equations are established based on coupled nonlocal elasticity theory, plasma diffusion equation, and moving ...

Optimal design for the artificial‐noise‐aided IRS‐MIMO‐OFDM secure communications
IET Communications, 2022 This paper discusses an artificial noise‐aided intelligent reflecting surface‐MIMO–OFDM system physical layer secure communication, in which two cases for the intelligent reflecting surface reflection coefficient models are considered separately, that is
