Refraction can cause optical illusions as the light waves appear to come from a different position to their actual source. The reverse is also true. A light ray speeds up as it passes from glass into ...

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

Abstract: In this paper, a theoretical analysis of orbital angular momentum (OAM) wave propagation properties in terms of reflection and refraction is introduced by decomposing OAM waves into infinite ...

Abstract: The refraction-diffraction of surface waves due to porous variable depth has been the subject of many investigations. In the present study, we extend the boundary-value problem of ...

This paper presents a comprehensive review, modeling, simulation, and evaluation of multipath propagation mechanisms—reflection, scattering, diffraction, and fading—relevant to 5G communication, with ...
