This book explores the rapidly evolving field of acoustic metamaterials, focusing on their ability to manipulate sound waves through asymmetric transmission, acoustic focusing, and acoustic asymmetric focusing. It introduces innovative research methods and achievements, such as the use of underwater plate-like metamaterials, airborne metamaterials, and phase-controlled metamaterials to achieve precise control over sound propagation in 2D and 3D spaces. Readers will be particularly interested in the novel applications of these materials in medical ultrasound, underwater...

This book focuses on the application of micro and nano biosensors in microsystems, where an introduction to the fundamentals of various types of biosensors should be considered an integral element.

After introducing the theoretical knowledge, authors discuss the application of biosensors in the detection of various biomolecules in combination with their own experience in the above research activities. In the process of introduction, authors keep abreast of the latest frontier research of biosensors to ensure that the book has sufficient novelty.

From a practical point of view,...
