Modulated electromechanics: large enhancements of nonlinearities
نویسندگان
چکیده
It is well-known that the nonlinear coupling between a mechanical oscillator and a superconducting resonator or optical cavity can be used to generate a Kerrnonlinearity for the cavity mode. We show that the strength of this Kerr-nonlinearity, as well as the effect of the photon-pressure force can be enormously increased by modulating the strength of the nonlinear coupling. We describe an electromechanical circuit where this enhancement could be readily realized.

متن کاملNonlinear optics of random metal-dielectric films
Surface-enhanced optical nonlinearities are studied in a semicontinuous film consisting of metal granules randomly distributed on an insulating substrate. The local fields are very inhomogeneous in such films and consist of strongly localized sharp peaks. In peaks ~‘‘hot’’ spots!, the local fields exceed the applied field by several orders of magnitudes resulting in giant enhancements of the op...
متن کاملThe importance of mechano-electrical feedback and inertia in cardiac electromechanics.
In the past years, a number cardiac electromechanics models have been developed to better understand the excitation-contraction behavior of the heart. However, there is no agreement on whether inertial forces play a role in this system. In this study, we assess the influence of mass in electromechanical simulations, using a fully coupled finite element model. We include the effect of mechano-el...

This paper presents a nonlinear analytical model for micromechanical silicon ring resonators with bulk-mode vibrations. A distributed element model has been developed to describe the dynamic behavior of the micromechanical ring resonator. This model shows the nonlinear effects in a silicon ring resonator focusing on the effect of large amplitudes around the resonance frequency, material and ele...
متن کاملClustering of nasopharyngeal carcinoma intensity modulated radiation therapy plans based on k-means algorithm and geometrical features
Background: The design of intensity modulated radiation therapy (IMRT) plans is difficult and time-consuming. The retrieval of similar IMRT plans from the IMRT plan dataset can effectively improve the quality and efficiency of IMRT plans and automate the design of IMRT planning. However, the large IMRT plans datasets will bring inefficient retrieval result. Materials and Methods: An intensity-m...
