The Particle Tracing Module extends the functionality of the COMSOL Multiphysics environment for computing the trajectory of particles in a fluid or electromagnetic field, including particle-field interactions. Any add-on module...
A scanning electron microscope samples images by scanning a target with a high-energy beam of electrons. The subsequent electron interactions produce signals such as secondary and back-scattered electrons that contain information about...
In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure...
This model shows how to use particle tracing to simulate convection-dominated particle flow through a small office setting.
Particle Tracing is used in conjunction with magnetic fields and pressure-driven microfluidic flow to calculate the separation of red blood cells from blood plasma using magnetophoresis. An array of soft iron rectangles on either side of...
An Einzel lens is an electrostatic device used for focusing charged particle beams. It may be found in cathode ray tubes, ion beam and electron beam experiments, as well as in ion propulsion systems. This particular model consists of...
Multipaction can occur when electrons are accelerated by a high frequency RF field into surfaces. Secondary electron emission can occur and under the right conditions there can be an exponential growth in the number of electrons. The...
A Luneburg lens, in the most general sense, is a spherically symmetric thick lens with a variable-index refracting structure which will form perfect geometrical images of two concentric spheres onto each other. The Luneburg lens has a...
This model demonstrates the use of optical tracing for studying optically large gradient-index structures with anisotropic optical properties. Additionally, the model introduces a smoothing technique for handling discontinuities of...
This model computes the trajectory of an ion in a uniform magnetic field using the Newtonian, Lagrangian and Hamiltonian formulations available in the Mathematical Particle Tracing interface.
