Abstract: Ventilated sound isolation platforms enabling asymmetric absorption have demonstrated great scientific significance and promising applicability. However, common designs composed of variant resonant meta-atoms present complicated frameworks and poor flexibility in operating frequency modulations, let alone… read more here.
