Modeling Periodic Electric Signals and Their Thermal Effects
Electrical pulse trains can be applied to human tissue for electroporation and thermal ablation. Learn how to model such signals via a Fourier transform approach.
Understanding the Transient Electromagnetic Excitation Options
Looking to model electrical signals that vary arbitrarily in time? We suggest using the Electric Currents interface. Learn why here.
Happy Birthday, Joseph Larmor
Joseph Larmor wrote on topics ranging from electricity and dynamics to the electron theory of matter. However, he is best known for his 1900 publication on aether and matter.
Full Acoustic Room Impulse Response of a Small Smart Speaker
The acoustic response of a small smart speaker can be modeled using the built-in hybrid FEM–ray coupling functionality in the COMSOL Multiphysics® software. Learn more here.
Developing Better Resonators for CMOS Technology
Sub-GHz technologies are used by the billions for home automation, infrastructure monitoring, and more. This growing demand calls for optimally designed RF filters and resonators.
Happy Birthday, Angelo Moriondo
How we brew espresso today is largely influenced by an inventor from the 1800s, who recognized the need to provide quick coffee service.
Stress Minimization: A Heuristic Approach for Improving Fatigue Behavior
2 models, a bracket and wheel rim, demonstrate a gradient-based optimization method that enables stress minimization to be used heuristically to improve fatigue behavior.
The Power of the Batch Sweep
Have you ever run a large parametric sweep on your workstation overnight, only to discover the next morning that the parametric solver is still not finished? Enter the batch sweep.
