Attenuation Behavior of Solid Dense Random Media at Microwave Frequencies

Abstract

To better understand scattering from nontenuous dense random media such as sea ice and snow, attenuation measurements have been performed on two different types of random media with ka values ranging from 0.5 to 0.7, and 1.5 to 2.1. The following paper describes, briefly, experimental results from wave propagation in plane slabs of finite thickness composed of: (1) a random distribution of identical, finite scatters; and (2) a random distribution of scatters with narrow size distribution. The aim of this paper is to present the observed behavior in terms of attenuation versus volume friction, and additionally, the behavior of attenuation versus frequency. Results presented in this paper are compared to the behavior reported by some earlier experiments where the medium properties are different.
