Breaking The Acoustic Resolution Limit With A Metamaterial Magnifying Lens

The acoustic microscope is a critical component for a variety of applications including quality control, medical imaging, biomedical sensors, and focused ultrasound surgery, owing to its ability to distinguish objects separated by a small distance. The notion of an acoustic microscope can be traced back to 1936 when Sokolov proposed a device to provide magnified views of a structure by high-frequency sound waves. However, the implementation was handicapped by contemporary technological restrictions. Despite the rapid development in this area, the...

The Use Of Metamaterials For New Information Systems

Metamaterial has gradually cemented its place in the past 20 years as an area of exciting research and drawn broad attention from the physics and engineering communities, owing to its exotic electromagnetic (EM) behaviors. However, metamaterials have conventionally been described by effective medium parameters and governed by physical principles. They can be compared to, in a sense, analog circuits from the circuit perspective, which obviously have some drawbacks such as worse noise-resistant performance, lower signal precision, and sophisticated design. Digital...
