Shape and Topology Optimization of Step Thrust Bearings
Step thrust bearings support axial loads in rotating machinery. Learn how to maximize the load capacity of these bearings with shape and topology optimization.
Building a Metalens Design App with COMSOL Multiphysics®
Here, we explore how to build a simulation app for reflective metalens design, which can easily be compiled into a standalone app.
Happy Birthday, Michiyo Tsujimura
In 1932, Michiyo Tsujimura’s thesis on the chemical components of green tea was approved by the Tokyo Imperial University — making her the first woman in Japan to receive a doctorate’s degree in agriculture.
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.
