Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers - raw measurement data

<p>The files in the archive relate to the frequency response data used in the graphical results presented in the paper &quot;Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers&quot; by Stanislav Sergeev, Romain Fleury, and Herv&eacute; Lissek.</p> <p>Data was recorded with the software: PULSE LabShop Fast Track Version 18.1.1.9 - 2014-01-16.</p> <p>File &quot;alpha_absorption.txt&quot; contains frequency response of absorption coefficient of active plasma metalayer tuned to 100% sound absorption (figure 3). First column - row number, second column - frequency in Hz, third column - magnitude.</p> <p>Files &quot;R_04.txt&quot;, &quot;R_07.txt&quot;, &quot;R_09.txt&quot; contain frequency response of complex reflection coefficient when plasma metalayer is tuned to various constant over frequency reflection coefficients (figure 4a). First column - row number, second column - frequency in Hz, third column - real part, fourth column - imaginary part.</p> <p>Files &quot;R_04_0cm.txt&quot;, &quot;R_04_05cm.txt&quot;, &quot;R_04_10cm.txt&quot;, &quot;R_04_15cm.txt&quot; contain frequency response of complex reflection coefficient when plasma metalayer is tuned to constant over frequency reflection coefficient of magnitude 0.4 and different linearly changing phases (figure 4b). First column - row number, second column - frequency in Hz, third column - real part, fourth column - imaginary part. File &quot;R_04_10cm.txt&quot; was measured at 4 cm further plane. To be consistent with the other data, phase should be corrected by 4 cm shift.</p>
