Using Degeneracy Breaking to Design a MEMS Biosensor
Researchers from Newcastle University in the U.K. used simulation to investigate the effects of material and geometric symmetry breaking in a degenerate mode sensor. Get the full story >>
Thermodynamic Equilibrium of Plasmas
Are you interested in modeling plasmas with the COMSOL® software? Get an overview of the different plasma types and when to use each of the interfaces available in the Plasma Module.
Enhancing the Design of Biconical Antennas with Simulation
Biconical antennas are an important component when conducting electromagnetic compatibility (EMC) testing for consumer electronics. RF simulation can be used to enhance their design.
Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems
Learn how to use scattering boundary conditions and perfectly matched layers to truncate domains for your wave electromagnetics problem — and which technique is best for your modeling scenario.
How to Perform a 3D Analysis of a Semiconductor Device
Open for a comprehensive introduction to performing 3D analyses of semiconductor devices in COMSOL Multiphysics®. We demonstrate with a bipolar transistor example.
Dielectrophoretic Separation
Dielectrophoresis is a phenomenon in which an electric field is used to control the movement of electrically neutral particles. Learn about how to model this effect in both DC and AC fields.
Improving the Power of Optical Systems via Component Design
Adaptive optics are used to improve the power of optical systems — beyond the obstacles imposed by the optical medium. See examples and learn how to model adaptive optics systems.
Magnetic Damping of a Vibrating Cantilever Beam
We discuss modeling a cantilever beam in a magnetic field. The beam has some structural excitation at the free end, which vibrates it at a constant frequency. Get details in this blog post.
