Frozen sound: An ultra-low frequency, ultra-broadband, non-reciprocal acoustic absorber

The files contains the main results found in the paper 'Frozen sound: An ultra-low frequency, ultra-broadband, non-reciprocal acoustic absorber'. 

Each file contain an absorption coefficient in the form of a vector with its corresponding frequency.

TA: Refers to the thermoacoustic absorber, i.e in the presence of cooling.

NoTA: Refers to the porous material without cooling.
