Abstract

Two fundamentally different nonlinear inversion techniques are implemented here to investigate the reconstruction of a dispersionless refractive profile from experimental reflection data. The first nonlinear technique used is approximate and based on the Riccati differential equation, and the second technique is exact and based on the Balanis integral equation. Neither of these techniques has been experimentally tested to date. Previous inversions have been applied to other methods and for the most part have been restricted to synthetic data. In this microwave experiment, band-limited frequency-domain reflection data are collected and used for the reconstruction of the refractive profile of a Plexiglas slab.
