Acoustics plays an important role in fundamental research and industrial applications such as medicine, communication, aerospace, ocean exploration, etc. In particular, it is irreplaceable in the fields of medical ultrasound and underwater acoustic communication, which are important to people's health. Precise and diversified acoustic field control is an important goal and key issue in this area. However, the classic acoustic control method is restricted by the properties of natural materials and cannot meet the requirement. Acoustic artificial structures provide a new way to break the limitations of natural materials and achieve special sound control, realizing properties that conventional materials do not possess.

Xue Jiang proposed and realized a multiplexing communication method based on orbital angular momentum which plays as a new degree of freedom to improve the efficiency and quality of acoustic communication. She developed a series of medical ultrasound devices that break through the conventional performance limits, proposed a multifunctional holographic converged wireless system to control implantable devices, and solved some difficult problems. The research results have been applied in the DiXing-2 Experiment of the Astronaut Research and Training Center, providing important theoretical and experimental foundations for bone loss of space station astronauts.

Jiang also introduced the concept of metasurfaces into acoustic systems and solved the fundamental problem of controlling large-wavelength sound waves with small-sized structures, breaking the paradox of variable refractive index and acoustic impedance matching. She made unique contributions to the use of and exploration of frontier physical effects of acoustic artificial systems.

Jiang has not only made outstanding contributions in the field of basic acoustic research, but the acoustic artificial structures she developed are also expected to achieve better ultrasound imaging and treatment effects in the near future, bringing good news to tumor patients.
