Calculating the spectral response strength of non-Hermitian systems with an exceptional point directly from wave simulations
Exceptional points are spectral degeneracies in open systems, which have attracted considerable attention in recent years. One reason for the attention is that physical systems with an exceptional point exhibit a strong spectral response to perturbations. This response can be quantified by a single...
