As counterparts to optical frequency combs, magnonic frequency combs could have broad applications if their initiation thresholds were low and the ‘teeth’ of the comb plentiful. Progress has now been made through exploiting so-called exceptional points to enhance the nonlinear coupling between magnons and produce wider magnonic frequency combs.

增强的波幅频率梳的生成

作为光学频率梳的对应物，如果其起始阈值较低并且梳的“齿”丰富，那么波幅频率梳可能具有广泛的应用。现在，通过利用所谓的特殊点来增强磁振子之间的非线性耦合并产生更宽的磁振子频率梳，已经取得了进展。
