Microwave Imaging Profilometry for Plasma Diagnostics

Microwave imaging can provide effective means for non invasive electromagnetic diagnostics of plasma showing several advantages with respect to traditional techniques. Although microwave imaging entails solution of a full wave inverse scattering problem, it can be addressed in a less complex (but not simpler) way considering the one-dimensional inverse scattering problem for microwave imaging profilometry (MIP). In this contribution, we describe a frequency difference domain approach for MIP and provide a possible 3D full wave experimental setup in order to make a step forward application of MIP against laboratory experimental data.
