ABSTRACT

Over the past decade there has been a great amount of research effort devoting to the topic of acoustic metamaterials (AMMs). The recent development of AMMs has enlightened the way of manipulating sound waves. Several potential applications such as low-frequency noise reduction, cloaking, angular filtering, subwavelength imaging and energy tunneling, have been proposed and implemented by the so-called membrane- or plate-type AMMs without mass attached. This dissertation aims to present developed analytical/semi-analytical models for square/rectangular shaped membrane- or plate-type AMMs without mass attached, arbitrarily shaped AMMs without mass attached, and heavy medium effect on the square/rectangular shaped membrane- or plate-type AMMs without mass attached. These analytical/semi-analytical models which can reveal behind physics and are powerful tools to be utilized to design AMMs. All derived models were verified by FEM models.

BIOGRAPHY

Tai-Yun Huang was born in March 18^th, 1984, Taiwan. He obtained his bachelor degree, majored in electrical engineering, from National Taipei University of technology in 2006. After finishing mandatory military in Taiwan 2008, he came to the U.S. and obtained his master degree, majored in Physics, from Pittsburg State University, KS, in 2011. From fall 2012, he came to North Carolina State University and started to pursue his PhD degree in Mechanical Engineering, specifically studying on acoustics which includes sound and plate-type structure interaction, plate-type structure vibration, and acoustic metamaterials design for noise reduction. He plans to obtain his PhD degree in the end of 2016. Out of work, he likes to hand out with family and friends to chat, travel, and exercise (work out, play basketball, play ping pong)
