La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
Whenever dimensions in waveguides become small compared to the viscous and thermal boundary layers it is necessary to model acoustics using thermoacoustics. In the present model the thermoacoustic wave field in a shallow uniform waveguide is modeled and compared to an analytical solution. Per saperne di più
A small building block of integrated photonics, i.e., a Silicon-on-Insulator taper, is considered. For a larger system design, it might be useful to determine the phase delay such a device introduces. Here, we showcase the layout needed to do it in COMSOL, including a proper Port ...

A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... Per saperne di più
SMA connectors are popularly used on printed circuit boards (PCB) for testing. This model shows how to excite an SMA connector on a microwave substrate and how to terminate a grounded coplanar waveguide (GCPW) with 50 ohm using a lumped port and an air-bridge. Per saperne di più
A tapered optical waveguide structure is used for matching two waveguides having different geometric cross sections and/or different material parameters. The tapered waveguide has one geometric cross section at the input plane and another cross section at the output plane. In between ... Per saperne di più
The model analyses the mode propagation within a nano slot waveguide. In a slot waveguide configuration, two high refractive index slabs (~3.48) are placed adjacent to the low refractive index slot (~1.44). Mode analysis was performed on a 2D cross section of a slot waveguide for an ... Per saperne di più
This is a model of an adapter for microwave propagation in the transition between a rectangular and an elliptical waveguide. Such waveguide adapters are designed to keep energy losses due to reflections at a minimum for the operating frequencies. To investigate the characteristics of the ... Per saperne di più
A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass ... Per saperne di più
This model demonstrates how to simulate the propagation of guided waves in a dielectric S-bent optical waveguide. The model demonstrates that the phase approximation, required by the Electromagnetic Waves, Beam Envelopes interface, can be numerically calculated by solving an additional ... Per saperne di più
In this model, a modal analysis is performed while parametrically sweeping the length of a waveguide from 0.5 um to 4 um to derive the dispersion curve for the anisotropic core. Both transverse and longitudinal anisotropy are considered in two different models. These models are ... Per saperne di più
