One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: One method of creating spring-like structures or inducing curvature in thin structures is to plate them to substrates that are under the influence of residual stresses.

The plating process can control this stress even for similar materials. One such device is the electrostatically Piezoelectric valves are frequently employed in medical and laboratory applications due to their fast response times and quiet operation. Their energy efficient operation, also dissipates little heat, which is often important for these applications.

This model shows how to model a This benchmark model computes the total force acting on a vibrating disc in the frequency and time domains and compares both results with expressions derived analytically. When the vibration amplitude is small enough that the system is linear the frequency and time domain results agree This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator.

The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially PMN-PT exhibit nonlinear strain as a function of electric field.

This 2D axisymmetry model uses a parametric sweep of voltage to This model shows how to create dispersion diagrams from simulation results by extending the tutorial Thin-Film BAW Composite Resonator.

The dispersion curve can be plotted against both real and imaginary values of the wave number, corresponding to the propagating modes and evanescent The measurement of S-parameter is commonly used to characterize such devices for RF applications.
