For the silver nanoparticle with the radius of 10nm, the phase shifts are consistent with the feature of a forced damped harmonic oscillator. For the large silver nanoparticle with the radius of 50nm, the magnitudes of the phase shifts have some deviations due to the nonuniform electric field ...
Using this master equation we show that, apart from brief transients, the resonator always behaves like a damped harmonic oscillator with a shifted ... DA Rodrigues,AD Armour - 《New Journal of Physics》 被引量: 42发表: 2005年 加载更多研究点推荐 Forced Damped Harmonic Oscillator Fourier Series...
In this study, first we construct the quasi-coherent states for a damped and forced harmonic oscillator and discuss the transition of the system from the damped oscillations to forced steady state oscillations. Second, we generalize the Caldirola-Kanai Hamiltonian into the new systems such as the ...
hi guys, doing damped and forced harmonic motion at college at the moment, but i don't do further maths...hence I'm a tad behind compared to those who do...

The response of a damped Duffing oscillator of the softening type to a harmonic excitation is analyzed in a two-parameter space consisting of the frequency and amplitude of the excitation. An approximate procedure is developed for the generation of the bifurcation diagram in the parameter space of...

Expression of Forced Simple Harmonic Motion Consider an external force F(t) of amplitude F0 that varies periodically with time. This force is applied to a damped oscillator. Therefore, we can represent it as, F(t) = F0 cos ωdt (I) Thus, at this time, the forces acting on the oscilla...
In this paper, time-delay effects on periodic motions of a periodically forced, damped, hardening, Duffing oscillator are analytically discussed through a semi-analytical method. The semi-analytical method is based on discretization of the differential equation of such a Duffing oscillator to obtain ...
Additionally, an external harmonic force will be applied to the oscillator with a time-varying mass. Not only solutions of the oscillator equation will be constructed, but also stability properties for the forced vibrations will be presented for various parameter values....
