Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

Abstract: We report free space, microwave measurements with varying incidence angle on a material that exhibits a negative index of refraction. The experiments measure the index of refraction directly ...

Schematic of a grazing incidence small and wide angle X-ray scattering (GISAXS/GIWAXS) experimental setup showing the incident (αi) and the scattered angles along the horizontal (2θf) and vertical (αf ...

Straight wave reflection from straight barriers, 80-231, approx 3 minutes Single straight pulses are reflected from a straight barrier placed parallel to the wave front, then at 35, 45 and 55 degrees.

Abstract: The relation between microwave backscatter and incidence angle estimated from observations of the advanced scatterometer (ASCAT) onboard the Metop satellites contains valuable information on ...
