Metamaterial Designs to Enhance Microwave Imaging Applications

This paper presents an innovative metasurface design for emerging microwave brain imaging applications, such as stroke detection and monitoring. We have modelled different metamaterial designs in diverse setups, and have simulated their interactions with EM waves using CST Microwave Studio®. Our results have shown an enhancement of penetration for the transmitted signals when the metamaterial film is placed in contact with skin tissue. These results suggest that our design can be a significant hardware advance towards scanners for brain imaging.
