In erbium-ytterbium fiber lasers with mirrors based on sets of optomechanical microoscillators, modes multi-frequency (up to five frequencies) synchronous self-oscillations are implemented. Microoscillators made in the form a silicon microbeams array quasi-equidistant spectrum elastic vibration excited by laser radiation pressure. A significant dependence spectral properties optical resonator h...

Purpose Microbeam radiation therapy is a preclinical concept in oncology. It spares normal tissue more effectively than conventional at equal tumor control. The field consists of peak regions with doses several hundred gray, whereas between the peaks (valleys) are below tolerance level. Widths and distances beams submillimeter range for microbeam therapy. A similar alternative beam widths milli...

In this work, an analysis of thermoelastic, homogeneous, and isotropic microbeams was conducted in the context non-Fourier heat conduction law. The first end microbeam based on a graphene strip, which connected to electrical voltage source. Under simple boundary conditions maintained by fixed side ratios, Lord–Shulman model generalized thermoelasticity applied. thermally loaded with source due ...

Electrostatically actuated microbeams have been studied by many researchers in the last few years. The aim of this study is to present an improved numerical analysis of the dynamic instability of a cantilever microbeam immersed in an incompressible viscous fluid. The finite element method is used for solving the vibrational equation of the microbeam and the potential functions of the fluids in ...
