Acoustic Metamaterials for Ultrasound Imaging and Biomedical Applications

  • Submission closed.

About this Research Topic

This research topic is focused on new concepts, technology and applications of acoustic metamaterials to enable new capabilities and improve the performance of ultrasound imaging in areas such as biomedical imaging and material testing. This article collection aims to collect new concepts and technology approaches towards the use of acoustic metamaterials for ultrasound imaging applications. New modelling, technologies, and applications, as well as article reviews compiling efforts in acoustic metamaterials for ultrasound applications are of interest for this collection. Extraordinary acoustic phenomena such as acoustic cloaking, subwavelength imaging, negative density, negative modulus, and acoustic holograms have been demonstrated with acoustic metamaterials. All these phenomena can have transforming capabilities in ultrasound imaging, especially in biomedical imaging and material testing. However, several challenges such as operation at higher frequencies, fabrication technologies, models that include real anatomical samples are required to integrate current ultrasound imaging technologies with new developments in acoustic metamaterials. Moreover, metamaterials can greatly enhance beamforming capabilities for therapeutic ultrasound applications, enabling better beam control and subwavelength focusing. Successful integration of acoustic metamaterials for ultrasound imaging and therapy can revolutionize biomedical applications capabilities with enormous impact in areas such as health-care and neuroscience and transport safety.


Keywords: Acoustic Metamaterials, Ultrasound Imaging, Acoustic Resonators, Acoustic Cloaking, Subwavelength Imaging, biomedical ultrasound


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
