Practical Chart for Harmonic Resonance Assessment of DFIG-Based Wind Parks
IEEE Transactions on Power Delivery, 2020Harmonic resonances in DFIG-based wind parks can be investigated by using extensive electromagnetic transient simulations, which is a time-consuming process. This paper shows that not all wind parks need such a detailed analysis.

Harmonic Resonance Enhanced Second-Harmonic Generation in the Monolayer WS2–Ag Nanocavity
, 2020The enhanced second-harmonic generation (SHG) from a monolayer WS2 coupled to a plasmonic nanocavity is experimentally and theoretically investigated. The nanocavity is comprised of monodispersed Ag nanocubes separated from an Ag film by a spacer Al2O3 ...

Resonant Perturbations of Harmonic Oscillation
Journal of the London Mathematical Society, 1986The paper considers the asymptotic form as \(x\to \infty\) of solutions of the mth order differential equation \[ \{(iD+a_ 1)(...)(iD+a_ m)+(- 1)^{m-1}r(x)\}y(x)=0\quad (a\leq ...

IEEE Journal of Solid-State Circuits
In this article, we propose a voltage-controlled oscillator (VCO) with a single three-coil transformer, featuring a common-mode (CM) resonance expansion and intrinsic differential 2nd harmonic output. In addition to a conventional transformer-based class-
