Abstract: We study the multifrequency excitation of an inclined marine riser under two-to-one and three-to-one internal resonances. The riser model accounts for the initial static deflection, self-weight, and mid-plane stretching nonlinearity. By tuning the initial applied… read more here.

Abstract: We analyze theoretically a network of all-to-all coupled polariton modes, realized by a trapped polariton condensate excited by a comb of different frequencies. In the low-density regime the system dynamically finds a state with maximal… read more here.

DOI: 10.1109/tim.2025.3602564
Abstract: Wear particle detection sensors utilizing single-frequency excitation have been widely applied. However, their accuracy in material and size identification remains suboptimal. This study proposes a multifrequency excitation method that enhances the accuracy of both material… read more here.
