From: Reduced-order modelling of parametric systems via interpolation of heterogeneous surrogates

Interpolation of Loewner ROMs in the original form. The pROM with order \(k = 21\) is obtained by interpolating nonparametric Loewner ROMs in the original form at \(p_1=10\) and \(p_2=268.3\). The FRFs at \(p_* =65.51\) are shown for comparison
