Description

Polar backscattering from a fiber-reinforced composite which contains regions of porosity, consists of several components. Roughly speaking these components can be attributed to effects of finite beam width, to the structuring of the material and to the existence of porosity. The backscatter amplitude strongly depends on the polar and the azimuthal angles, which together define the position of the transducer. It has been shown experimentally that the backscatter amplitude shows a steep peak when the incident beam is normal to the fiber direction [l]–[4].

Analytical Treatment of Polar Backscattering from Porous Composites

La Jolla, CA

Polar backscattering from a fiber-reinforced composite which contains regions of porosity, consists of several components. Roughly speaking these components can be attributed to effects of finite beam width, to the structuring of the material and to the existence of porosity. The backscatter amplitude strongly depends on the polar and the azimuthal angles, which together define the position of the transducer. It has been shown experimentally that the backscatter amplitude shows a steep peak when the incident beam is normal to the fiber direction [l]–[4].
