"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)"The objective of this research is to develop the fundamental scientific and engineering principles that will form and drive the development of k-space multifunctional acoustic wave devices as potential components in telecommunication technology with high level functionalities. The approach is based on the use of phononic crystals as parts of acoustic wave devices that can produce transformative k-space (real space) functionalities in addition to the more common spectral (temporal) functions. These novel functions arise from properties of phononic crystals such as zero or negative angle refraction as well as generation of phase locked multiple beams. This research will combine theoretical-computational methodologies and experimental techniques. The research objectives will be met by demonstrating experimentally prototype functional structures and devices. This research?s intellectual merit resides in the k-space functionality of the devices. In contrast to traditional spectral functions these new functions will transform the field of acoustic wave devices by enabling spatial filtering, beam multiplexing and logic operations in compact structures and devices as practical miniaturized and integrated components in acoustic wave systems. The investigators will conduct the research in a global context and will expose graduate and undergraduate students to international collaborations through exchange as part of a Centre National de La Recherche Scientifique (France)-University of Arizona International Associated Laboratory. The investigators will build on experience in the development of Do-It-Yourself technology kits on audible phononics to support outreach activities at high schools and science fairs with the aim of promoting science and engineering education and careers among the ethnically diverse Tucson community.

“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的”这项研究的目标是制定基本的科学和工程原理，这些原理将形成并推动k空间多功能声波器件的发展，作为具有高水平功能的电信技术的潜在组件。该方法基于使用声子晶体作为声波器件的一部分，除了更常见的谱（时间）函数之外，该声波器件还可以产生变换的k空间（真实的空间）函数。 这些新的功能产生的声子晶体的性质，如零或负角折射，以及锁相多光束的产生。这项研究将结合联合收割机理论计算方法和实验技术。研究目标将通过实验演示原型功能结构和设备来实现。 这项研究？的智力价值在于器件的k空间功能。与传统的谱函数相比，这些新的函数将通过在紧凑的结构和设备中实现空间滤波、波束复用和逻辑操作来改变声波设备的领域，作为声波系统中的实用小型化和集成部件。 研究人员将在全球范围内进行研究，并将通过交流使研究生和本科生接触国际合作，作为法国国家科学研究中心-亚利桑那大学国际联合实验室的一部分。 调查人员将建立在自己动手技术套件的开发经验，以支持在高中和科学博览会的推广活动，旨在促进科学和工程教育和职业之间的种族多元化图森社区。
