Fig. 3: Comparison among theoretical, numerical and experimental results for SAM density on the waveguide cross-section.

From: Realization of acoustic spin transport in metasurface waveguides

Fig. 3

Theoretical results, numerical simulations and experimental measurements coincide with each other very well. The theoretical results of SAMs are from the analytic expression Eq. (2). The experimentally SAM density profile sy is measured for k > 0 in the frequency 2.9 kHz (Red circle cases in Fig. 2(c)).
