Bio-Inspired Ultra-Compact Acoustic Transmitter - Bubbles as a Means of Weak-Source Amplification

申请人有一个在EPSRC中心的全额资助的学生在未来超声工程（FUSE）博士培训正式报价是医疗和工业超声中心（CMIU）之间的合作伙伴关系，格拉斯哥大学和超声工程中心（CUE），斯特拉斯克莱德大学。一个PhD项目已被接受。项目摘要如下。对于与它们产生的波长相比尺寸小的水下声学装置的需求日益增长。目前在较低频率下进行大功率传输的方法依赖于使用大位移或大辐射面积，这对于真正紧凑的装置来说是不可行的。超声波工程中心的斯特拉斯克莱德电子和电气工程系已经与泰勒斯海事使命系统公司一起研究了较小的水船夫雄性昆虫（Scholtzi），其通过有效地产生水下声音进行通信，尽管其远小于其输出的波长。这是通过动物使用其空气供应作为二级放大器来实现的。该项目就是要复制这种现象。

The applicant has a formal offer for a fully-funded studentship in the EPSRC Centre for Doctoral Training in Future Ultrasonic Engineering (FUSE) is a partnership between the Centre for Medical and Industrial Ultrasonics (CMIU), University of Glasgow and the Centre for Ultrasonic Engineering (CUE), University of Strathclyde. A PhD project has been accepted. The project summary is as follows. There is a growing need for underwater acoustic devices that are small in size compared to the wavelength that they produce. Current methods for high-power transmissions at lower frequencies rely on the use of large displacements or a large radiating area which is not feasible for a truly compact device.Work has already been done at the Strathclyde Department of Electronic and Electrical Engineering in the Centre for Ultrasonic Engineering in conjunction with Thales Maritime Mission Systems studying the lesser water-boatman male insect (Micronecta scholtzi ) which communicates through efficient generation of underwater sound despite being much smaller than the wavelength of its output. This is achieved by the animal using its air-supply as a secondary amplifier. The project is to replicate this phenomena.
