READ ME File For Cost surface plots of the effective material properties Dataset DOI: 10.5258/SOTON/D2224 ReadMe Author: Joe Tan, ISVR, University of Southampton ORCID ID: 0000-0003-0148-6287 This dataset supports the thesis entitled: Active Acoustic Metamaterials for High Performance Noise Control AWARDED BY: Univeristy of Southampton DATE OF AWARD: 2022 DESCRIPTION OF THE DATA A video file that shows the cost surface plots of the effective material properties against the real and imaginary parts of the single monopole and single dipole control source strength at each frequency over the the presented bandwidth. This data has been collected using Matlab, where the Matlab script calculates the effective material properties from a range of the real and imaginary parts of the control source strength. This dataset contains: A video file that shows the cost surface plots of each effective material property against the real and imaginary parts of the corresponding control source strength.
