A lattice Boltzmann (LB) method based on the linearized Boltzmann Bhatnagar-Gross-Krook equation for numerical simulation of oscillatory (unsteady) Stokes flow is proposed. Unlike the conventional (nonlinear) LB method that utilizes the time domain exclusively, the proposed method is formulated in the frequency domain to allow for direct access to the complex-valued stress, force, and velocity ...

This paper proposes the development of a Raman spectroscopy system which has capabilities to characterize the motion of high frequency MEMS/NEMS and devices without surface features. Raman spectroscopy is being increasingly used as a technique to characterize such devices to overcome inconveniences of other optical measurement techniques which include laser vibrometer, stroboscopic imaging, int...

FEI Helios NanoLab 600i microscope with Kleindiek MM3A-EM micromanipulators, controlled by microscope PC connected to Keithley 2400 Source Meter, has been used in our experiments. Due to limited space only several examples of FIB/SEM processes that have been conducted are presented here. They proof the great advantage of this technology in modifying single structures in short time. Streszczenie...
