A new copper "metamaterial" can overcome some of the limitations of acoustic microscopes and imagers, including ultrasound imagers. Researchers have designed and built a metamaterial that improves the picture quality of sonography by a factor of 50. The material, composed of copper tubes, resonantly channels evanescent acoustic waves to a detector, capturing more detail than is carried by propagating sound waves.
