Abstract

A microwave imaging process, and a system controlled by an associated software product, generate microwave data and estimate initial ϵr and distributions to form current ϵr and σ distributions. A forward solution is determined based on the current ϵr and σ distributions, utilizing a finite difference time domain method. Computed field values are extracted, and a tolerance metric is determined. If the tolerance metric does not meet a preselected limit, a Jacobian matrix is calculated, ϵr and σ distributions are recalculated to form current ϵr and a distributions, and iterating until the tolerance metric meets the preselected limit.
