The importance of moisture content for sediment dynamics in coastal environments is well documented, particularly reference to aeolian transport (Davidson-Arnott, 2005). Tidally-induced changes partially saturated environments, such as beaches, cause significant surface shear strength through the development suction stresses, which can affect erodibility (Sassa and Watabe, 2007). Thus, accurate...

In this paper, a new technique for measuring the effective propagation constant of dense random media is presented. This technique involves two major steps: 1) measurement of the mean bistatic scattered field of a cluster of the random medium confined in a spherical boundary and 2) characterization of the complex permittivity for a homogeneous dielectric sphere having identical radius and bista...

Jute textile is made from natural fibres and is known for its strength and durability. To determine if jute could be used as a substrate for microstrip antennas, its electromagnetic characteristics (permittivity and loss tangent) are measured in the band of 1 GHz to 5 GHz. The obtained data are used to compare the performances of a simple rectangular patch antenna resonating at 2.45 GHz on jute...

Recent advances in satellite remote sensing at near-millimeter and sub-millimeter wavelengths (~100-3000 GHz) require accurate complex permittivity for ice and liquid water at these frequencies for different temperatures, especially for cold atmospheric conditions. This paper summarizes the existing experimental permittivity data in the literature, and provides an updated empirical ice permitti...

Measurement of multilayer material properties with fringing electric field dielectrometry sensors requires the processing of terminal admittance data from multiple electrode pairs. The choice of the algorithmic approach for data analysis is critical because of a high sensitivity to small measurement uncertainties. While individual channel uncertainties are usually within a reasonable instrument...

Two-Thickness-Method (TTM) based on an open-ended coaxial probe was investigated with an emphasis on uncertainty analysis to perfect this technique. Uncertainty equations in differential forms are established for the simultaneous measurement of complex electromagnetic (EM) parameters in the systematical consideration of various error factors in measurement. Worst-case differential uncertainty e...

Electrical capacitance tomography (ECT) attempts to reconstruct the permittivity distribution of the cross-section of measurement objects from the capacitance measurement data, in which reconstruction algorithms play a crucial role in real applications. Based on the robust principal component analysis (RPCA) method, a dynamic reconstruction model that utilizes the multiple measurement vectors i...
