Comparative Assessment of Electro-Mechanical and Solid-State Switching Matrices for a Portable Microwave (pMWI) Scanner in Brain Imaging Applications
This work systematically evaluates two different switching matrices, dubbed herein as EMech and Correlator. One is based on ad-hoc electromechanical switches, the other on off-the-shelf solid-state ones [1]. These matrices interface a 2-port Vector Network Analyzer (VNA) and a 22-antenna array of a low-complexity portable microwave imaging (pMWI) system for brain monitoring [2], falling into to the category of multistatic system with switching network [3]. Hence, a whole $22 \times 22$ scattering matrix is sequentially filled by $2 \times 2$ segments.
