This paper investigates the computation of the forced response of elastic open waveguides with a numerical modal approach based on perfectly matched layers (PML). With a PML of infinite thickness, the solution can theoretically be expanded as a discr

A Step Frequency Radar (SFR) is used for assessing the compaction of Hot Mix Asphalt (HMA) layers. The system is composed of a network analyser and an Ultra Wide Band (UWB) antenna placed above the road surface. The measurements are carried out on a

Contribution of leaky modes in the modal analysis of unbounded problems with perfectly matched layers

The modal analysis of wave problems of unbounded type involves a continuous sum of radiation modes. This continuum is difficult to handle mathematically and physically. It can be approximated by a discrete set of leaky modes, corresponding to imprope

The main objective of this work is to assess the capability of electromagnetic (EM) methods based on wave propagation to determine the compaction of hot mix asphalt (HMA) specimens. It is to be recalled that rocks are the main component of HMA. We be
