Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components
Advanced Engineering Materials, EarlyView.This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

Explaining negative refraction without negative refractive indices
, 2017 Negative refraction through a triangular prism may be explained without assigning a negative refractive index to the prism by using array theory. For the case of a beam incident upon the wedge, the array theory accurately predicts the beam transmission ...

Reconciliation of generalized refraction with diffraction theory. [PDF]
Optics Letters, 2012 When an electromagnetic wave is obliquely incident on the interface between two homogeneous media with different refractive indices, the requirement of phase continuity across the interface generally leads to a shift in the trajectory of the wave. When a

Advanced Engineering Materials, EarlyView.This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Using microwave refraction to determine local inhomogeneities of a rotating plasma
Nukleonika, 2023 To determine the local inhomogeneities of a rotating plasma, the method based on microwave refraction was used. The method is based on spectral and correlation analysis of the reflected signals from the rotating plasma layer at normal and inclined ...

, 2007 Refraction at a smooth interface is accompanied by momentum transfer normal to the interface. We show that corrugating an initially smooth, totally reflecting, non-metallic interface provides a momentum kick parallel to the surface, which can be used to ...

Introduction to “Refraction” [PDF]
Refract: An Open Access Visual Studies Journal, 2018 Refraction. The word evokes notions of light, optics, wave transmission, energy, and oblique angles. It is used in the field of physics to refer to the way a wave changes direction upon contact with a new medium through which it is transmitted. For instance, when sound waves hit the surface of water, their frequency changes—you may have experienced ...
