Abstract
This paper demonstrates a novel passive wireless biosensor based on a sub-terahertz photonic crystal resonator. The sensor achieves a reading range of up to 0.9 meters and wide acceptance angles, enabling stand-off detection of sub-micrometer thin-film proteins. This technology offers a potential low-cost solution for wireless sensor networks monitoring airborne pathogens, facilitating pre-infection detection and disease prevention.
