The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
A circularly polarized GHz wave is incident on a layer of cold magnetized plasma. Depending on the operating frequency and plasma state, the incident wave can excite a set of waves with different polarizations. The resulting reflection and transmission characteristics can be of interest ... Read More
Cascaded cavity filters provide much better bandpass filter performance than single cavity filters. This example demonstrate how to use shape optimization to optimize three rectangular cavity filters coupled via slots. The calculated S-parameters show excellent out-of-band rejection. Read More
This example model demonstrates shape optimization of a cavity filter using the Transformation feature, so the boundaries remain flat and angles do not change. The optimization considers both insertion loss and out-of-band rejection. The optimized shape is verified using a different mesh ... Read More
