Results of studies on micro-focused X-ray beam diagnostics using an X-ray beam imaging (XBI) instrument based on the idea of recording radiation scattered from a thin foil of a low-Z material with a lensless camera are reported. The XBI instrument captures magnified images of the scattering region within the foil as illuminated by the incident beam. These images contain information about beam s...

We present and discuss the results of some numerical simulations dealing with wave motion in one-dimensional pantographic media, also known as beams. Specifically, analysis is carried out large displacements regime beams are modeled by using a completely discrete approach. Nonlinear vibrations induced transversal impulse studied. A simple yet efficient time-stepping scheme was used to reconstru...

The kinematics and the balance equations for multiphase micro-architectured materials such as foams, textiles, or beam-like structures exhibit a peculiar macroscopic behavior. The topology and mechanical properties of their structural constituents at the microscale induce this behavior. The derivation of the effective mechanical properties of 2D and 3D lattices made of articulated beams is here...

In this study, the design and analysis of micro beam is carried out using COMSOL multiphysics. The current passing through distributes heat energy due to its resistance that pushes entire desired distance thermal expansion. This expansion varies depending on amount emitted temperature. purpose model created estimate temperature increase required cause displacement in proposed software. addition...

We report on an optical setup to generate multi-Bessel beam profiles combining a refractive axicon and spatial light modulator. Based their particular profile, Bessel beams offer advantageous properties for micro drilling processes internal volume processing, especially transparent materials. In addition, the laser power of industrial, ultrashort pulsed lasers has increased significantly over l...
