Examination of the virtues of parametric energy coupling in wave energy conversion

open access: yesInternational Marine Energy Journal, 2022
Parametric resonance has been observed, both numerically and experimentally, in various studies of wave energy converters (WECs). Large heave motions induce a periodic variation in the metacentric height of a WEC body and, consequently, cause a harmonic

Modelling of Parametric Resonance for Heaving Buoys with Position-Varying Waterplane Area

open access: yesJournal of Marine Science and Engineering, 2021
Exploiting parametric resonance may enable increased performance for wave energy converters (WECs). By designing the geometry of a heaving WEC, it is possible to introduce a heave-to-heave Mathieu instability that can trigger parametric resonance.

Simplified Mathieu’s equation with linear friction [PDF]

open access: yesINCAS Bulletin, 2016
Consider a second order differential linear periodic equation. The friction coefficient is real positive constant. Some transformation of the solution and its first derivative allow writing two-order differential equations with void friction coefficients.

Modal Behavior of Microcantilevers Arrays with Tunable Electrostatic Coupling

open access: yesActuators, 2023
We analyse the spectral content and parametric resonant dynamics of an array of elastically and electrostatically coupled interdigitated micro cantilevers assembled into two identical half-arrays.

Adaptive Properties of a Ferromagnetic Single-Domain Grain in Alternating Magnetic Fields

open access: yesIEEE Access, 2023
A general self-consistent theory of adaptive properties of a ferromagnetic single-domain grain in alternating magnetic fields is constructed. Thresholds of new family of parametric instabilities of all orders are calculated. It is shown that the level of

How parametric resonance mechanism follows quench mechanism in disoriented chiral condensate [PDF]

open access: yes, 2001
We show how parametric resonance mechanism follows quench mechanism in the classical linear sigma model. The parametric resonance amplifies long wavelength modes of the pion for more than $10 fm/c$.

Study of the Influence of Nonlinear Moments upon Intensity of Parametric Roll

open access: yesJournal of Marine Science and Engineering, 2022
Hydrodynamical analysis of the conditions for the occurrence of chaotic ship roll, leading in some cases to the capsizing of the vessel, showed that such conditions are most likely to occur in the zone of the main parametric resonance of the roll when ...

Parametric resonance in tunable superconducting cavities [PDF]

open access: yes, 2013
We develop a theory of parametric resonance in tunable superconducting cavities. The nonlinearity introduced by the SQUID attached to the cavity, and damping due to connection of the cavity to a transmission line are taken into consideration. We study in

Plasmonic Parametric Resonance [PDF]

open access: yes2018 IEEE Photonics Conference (IPC), 2018
We introduce the concept of Plasmonic Parametric Resonance (PPR) as a novel way to amplify high angular momentum plasmonic modes of nanoparticles by means of a simple uniform optical pump. In analogy with parametric resonance in dynamical systems, PPR originates from the temporal modulation of one of the parameters governing the evolution of the state ...
