Electromagnetic bench based on ETSA antennas for civil engineering materials tomography
Résumé
In this work, we are interested in density reconstruction of road samples, aiming to guarantee road reliability. To do so, a joint work between Routes de France and Cerema has led to an electromagnetic (EM) bench, based on Exponentially Tapered Slot Antennas (ETSA). A mathematical inversion model is used to find the permittivity from antennas parameters, using simulation of electromagnetic waves scattering. From this permittivity, one can recover the density via the Complex Refractive Index Model (CRIM).
