Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

Vibrational resonance is a phenomenon in which the response of a nonlinear system to a weak low-frequency signal is significantly amplified by an appropriately tuned high‐frequency excitation. This ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...

Quantitative characterization of nanomechanical properties has invariably been a holy grail for atomic force microscopy. This article explains some of the industry’s earlier attempts made at ...

In the event of a breakdown, any number of issues may be the culprit, but there’s one in particular that’s particularly challenging to diagnose: resonance. Resonance can be a problem in any machine, ...

This file type includes high resolution graphics and schematics when applicable. Generating a high-frequency magnetic field can be quite a challenge due to an assortment of technical issues. At high ...
