Your Guide to the Physics Interfaces and Studies in the RF Module

April 19, 2019

The RF Module includes 4 physics interfaces and studies that you can use to analyze electromagnetic wave propagation and resonance behavior in your RF analyses.

Your Guide to Lumped Ports in the RF Module

April 12, 2019

Your guide to the 4 different types of lumped ports that you can use for your RF analyses, as well as the different modeling scenarios in which each type is applicable.

Fine-Tuning the Design of Piezoelectric Transducers with Simulation

April 5, 2019

A variety of use cases and a variety of physics: Piezoelectric transducer designs need to account for electric currents, pressure acoustics, stress-strain, and acoustic-structure interaction.

How to Synthesize the Radiation Pattern of an Antenna Array

April 4, 2019

You can study and prototype a phased array antenna without analyzing the entire structure through a full 3D wave equation (saving time and computational costs) by using an antenna array factor.

How to Simplify a Two-Port Device Model Using a Touchstone File

April 3, 2019

Say you’re modeling a two-port device and want to reduce the computational resources involved. We demonstrate one way to do so, involving a Touchstone file…

Modeling Heat Transfer in Thin Layers via Layered Material Technology

April 1, 2019

We answer some questions you may have about the Layered Material functionality in the COMSOL® software: What does it do? How do you update existing models? How do simulations benefit from it?

RF Module Part Library: An Easier Way to Model RF Devices

March 28, 2019

Sometimes, your models need to include connectors. Instead of spending time creating geometries for each connector, you can simply add them from the Part Library.

Performing a Multiphysics Analysis of a Thermal Microactuator

March 8, 2019

To design an optimized thermal microactuator for use in a specific device, you need to account for tightly coupled electrical, thermal, and structural phenomena in your analysis.
