A noncontact electrostatic probing technique using a scanning probe microscopy cantilever is shown to actuate and detect the resonant behavior of micromachined resonator. The method capable characterizing resonator with frequency much greater than that cantilever. coupled oscillator model developed for this system describes response test as detected through probe, including fourth-power dependence on drive voltage. veracity demonstrated comparison experimental data obtained from ten times...
The present study compares the critical initiation energy predicted by curvature (CC) and decay rate (CDR) models. To ensure a fair meaningful comparison between these two theoretical approaches, Taylor–Sedov blast wave model, which enables us to relate state of point source, has been employed in both Simplified as well detailed chemical mechanisms were for comparison. By using same ratio calculated with CC CDR models was found be one orders magnitude smaller than results previous studies....
This article describes a scanning probe microscopy technique for quantitative high-speed voltage wave form measurement inside an operating integrated circuit. Internal signals are determined by sensing the local electrostatic force on noncontacting micromachined cantilever that is closely positioned above circuit test point. Amplitude modulation based downconversion employed to measure repetitive high-frequency which can have bandwidth much greater than mechanical response of probe. A...
Laminar flame speed is commonly measured using the spherically expanding technique. The non-ideal shape of initial kernel may have a significant influence on subsequent propagation. In present study, propagation evolution ellipsoidal initiated from an was simulated with following linear stretch relation. effects two components for total rate, i.e. curvature and tangential stretch, were investigated. Different ideal spherical flame, which excludes effect flow, can be negative same order as...
Dynamic mode electrostatic force microscopy is a technique capable of measuring the internal voltage signals high-speed integrated circuits. Circuit are extracted by utilizing localized nonlinear Coulomb acting on microfabricated probe that closely positioned above circuit test point. Equivalent time sampling repetitive high-frequency signals, can have bandwidth much greater than mechanical response probe, achieved driving with amplitude-modulated pulses. Currently, dynamic microscopes...
