The demand for personalized and non-invasive technologies for diagnostics of brain-related diseases is a challenge involving multiple research fields. In this context, emerging electromagnetic (EM) techniques are receiving increased attention . Among these techniques, microwave imaging (MWI) has the potential to address specific clinical needs such as intra-cerebral hemorrhage (ICH) detection and monitoring. The success of an MWI brain scanner is strongly dependent on its hardware characteristics. For instance, to achieve a device capable of detecting a hemorrhage inside the brain, array of antennas immersed into a coupling medium are typically used to transmit microwaves in the 0.5-1.5 GHz frequency range into the brain tissue and receive the resulting scattered signal . In addition, our previous studies have shown that metasurface (MTS) structures can be used to enhance transmission and couple the incident power into the region of interest .
