Summary - Web del proyecto iScat

The goal of this project is to provide novel approaches and enabling technologies and techniques (design, fabrication and measurement) for electromagnetic (EM) imaging, intending to foster the usability of current and potential new applications. This aim is conducted through the development of experimental prototypes for EM imaging in terms of demonstrators to validate the proposed techniques as well as to consider their applicability.

Understanding the imaging as the capability of extracting information about profile and/or constitutive parameters of the object-under-test from the scattered fields, and based on the experience of the research group on the inverse radiation problem, physical insight studies, virtual prototyping (computer tools) and experimental characterisation of inverse scattering constitute the methodology for predicting the applicability and possibilities associated to the proposed EM imaging technologies.

The project comprises four, functionally sequential but interrelated, steps 1:

Theoretical studies concerning a Generalized Signal & Systems Theory scheme focused on generalizing models of physical problems and the analysis of real and complex variable techniques applied to EM problems, and their relationship with the inverse problem (WP1: Theoretical Analyses in Real and Complex Variable).

Development of integral equation-based inverse scattering methods for retrieving profile and/or constitutive parameters, including validation of the proposed methods from numerical and/or simulated field data (virtual prototyping) (WP2: Algorithms and Techniques for Electromagnetic Imaging).

Design and manufacturng of novel subsystems (compact range probes for scattering setups, frequency beam scanning antennas, near field focused antennas, GPU programming of inverse techniques) for EM imaging (WP3: Subsystems and Devices for Imaging).

Imaging measurement setups demonstrators using different scanning approaches and techniques (developed inverse scattering algorithms, probe correction, phaseless) at microwave, millimetre and submillimeter frequencies (WP4: Imaging Measurement Setups -uwave, millim, submillim).

Additionally, due to the (i) number of researchers, (ii) the involved institutions and EPOs, and (iii) the nature of the Project involving from theoretical tasks to measurement campaigns in facilities, a specific work package (WP0) has been considered with specified coordination and networking tasks (internal, with other institutions and labs, industry and dissemination to society).
