Marine propeller can cause excitation or deexcitation of resonator in front. As EM and hydrodynamics are quite similar, could we cause deexcitation of excited resonator by some antenna to which we can also practically apply time symmetry e.g. helical?
Radiotelescopes see also negative signals e.g. https://arxiv.org/pdf/2107.02695 - could they be explained by such caused deexcitation?
