西安电子科技大学高频电子线路课件chapter8 Oscillators
We investigate the existence and stability of the in-phase and out-of-phase modes for parameters ? > 0 and k > 0. To this end we use Floquet theory and numerical integration. Surprisingly, our results...
We study the dynamics of a system of four coupled phase-only oscillators. This system is analyzed using phase differ-ence variables in a phase space that has the topology of a three-dimensional torus....
Thispaperdealswithaclassofconservative nonlinear oscillators of the form ¨ x(t) + f (x(t)) = 0,where f (x) is analytic. A transformation of time fromt to a new time coordinate τ is defined such that p...
We study a system of three limit cycle oscillators which exhibits two stable steady states. The system is modeled by both phase-only oscillators and by van der Pol oscillators. We obtain and compare t...
he dynamics of a ring of three identical relaxation oscillators is shown to exhibit a variety of periodic motions, including clockwise and counter-clockwise wave-like modes, and a synchronous mode in ...
We investigate the existence, stability and bifurcation of phase-locked motions in a ring network consisting of phase-only oscillators arranged in multiple simple rings (sub-rings)which are themselves...

wo vibrating bubbles submerged in a fluid influence each others’ dynamics via sound waves in the fluid. Due to finite sound speed, there is a delay between one bubble’s oscillation and the other’s. Th...
The nonlinear dynamics of micromechanical oscil-lators are explored experimentally. Devices consist of singly and doubly supported Si beams, 200nm thick and 35 μm long.When illuminated within a laser ...
We propose a class of problems in nonlinear vibrations re-lated to avoiding undesirable hysteresis and jump phenomena by designingan oscillatorfor whichthe backbone curve is a straight vertical line.
Frequency locking and other phenomena emerging from nonlinear interactions between mechanical oscillators are of scientific and technological importance. However, existing schemes to observe such beha...
In this study we investigated the effects of different morphological configurations on a robot swinging task using van der Pol oscillators. The task was examined using two separate degrees of freedom ...
We report on oscillators and amplifiers based on all-silica singlemode, large mode area photonic bandgap fibers elaborated by the modified chemical vapour deposition process.
We describe a 230nm tunable fiber optical parametric oscillator (FOPO) using an 8ps pump laser. The FOPO generates 2-4ps pulses with conversion efficiency as high as 20%. The output spectrum exhibits ...
