a The AGP as a function of the bump width. The offset distance is \(\delta =0\), and the accommodation coefficient is \(\alpha =0.01\). b The AGP as a function of the offset distance \(\delta\). The bump size is \(0.1H\times 0.2H\). In both figures, the unit channel size is \(H\times H\). c The AGP as a function of the channel length. The bump size is \(0.1H\times 0.2H\), and the offset distance is \(\delta =0\)
