Spectra taken in saturated and disordered states exhibit a series of resonances with characteristic magnetic field dependencies. Making use of micromagnetic simulations, we identify resonances that reflect the spin-solid-state and monopole-antimonopole pairs on Dirac strings. The latter resonances allow for the generation of highly charged vertices in ASIs via microwave-assisted switching. Our findings open further perspectives for fundamental studies on ASIs and their usage in reprogrammable magnonicsmagnonicsartificial spin iceferromagnetic resonancespin dynamicsMagnetization dynamics of topological defects and the spin solid in a kagome artificial spin icetext::journal::journal article::research article
