Practical problems in the time-domain probing of lossy dielectric media
Résumé
Interest in time-domain probing of a lossy dielectric medium by means of optimization processes has been shown in former papers. Some problems related to the application of such techniques to realistic situations are envisaged. Screening effects due to losses are first investigated, and a setup (perturbed line) is presented to reduce them. The influence of a finite extent of the illumination, implied by classical wave applicators, is then discussed.
