Parameter [GAMMA] is crucial to distinction between the dispersion type following the acoustic dispersion branch.
Furthermore, the company is also expert in the treatment of releases of gas under pressure for venting, reducing the acoustic dispersion of fluid lines and low output silencers.
Because this new mode with its acoustic dispersion allows light to be contained on small surface areas and in a broad frequency range, it has implications for research in nano-optics and photonics applications.
Such behavior is characteristic of liquids with acoustic dispersion due to changes of molecular conformation or restructuring processes (7, 8).
This might be due to the fact that according to the dispersion analysis carried out in [18], the FSE has besides the acoustic dispersion curve, a second higher frequency curve.
