Tutorial Package Has 20 New Models for Antenna Design, Plasmonics, and Benchmarking Electromagnetics Simulations
COMSOL, Inc. announced the release of a new edition of its RF Module tutorials for its flagship product, COMSOL Multiphysics. The tutorial package has been enhanced with 20 new models that demonstrate how to leverage the RF extension module when designing and analyzing antennas and plasmonic technologies.
Additionally, the new tutorial package comes with a suite of benchmarking tools, enabling users to assess the accuracy of their engineering simulations developed with the RF Module against established reference points. With the 20 new models, the tutorial library for RF Module now provides more than 50 example models, all of which are available for immediate download at http://www.comsol.com/showroom/product/rf/.
“It is great to provide our growing base of RF Module users with a brand new tutorial package,” says Walter Frei, PhD applications manager at COMSOL. “More and more engineers and scientists have made COMSOL Multiphysics their simulation platform for researching and developing emerging technologies such as metamaterial and plasmonics modeling. One reason users cite for the popularity of COMSOL Multiphysics in these applications is the flexibility of the user interface, which allows for anisotropic materials, negative permittivity and permeability. They also cite the software's general and highly automated solver technologies. We're delighted to show our user community how they can better apply the RF Module to RF and Microwave simulations.”
Among the new tutorials now available are microstrip patch antenna, double-layered dielectric lens radome, branch line coupler, evanescent-mode cavity filter, and dielectric resonator antenna. “These examples should really help users get kick-started with COMSOL Multiphysics and the RF Module,” says Jiyoun Munn, microwave applications expert at COMSOL. “They show you step-by-step how to quickly create the geometry and set up material properties, ports, and other boundary conditions. There's even an emphasis on production of relevant S-parameter and far-field radiation pattern outputs, which are vital for making informed design decisions.”
“The tutorials also show off COMSOL’s amazing visualization capabilities,” adds Mr. Munn. “COMSOL lets you visualize any type of field quantity anywhere in your model easily. This capability helps users build confidence in their analyses while developing an intuitive feel for their models quickly.”
Benchmarks
A number of classic benchmarks are a standard part of the new RF Module tutorial package. The benchmarks come with step-by-step instructions that make it easy for users set-up their evaluations. Among the areas of interest addressed by new example benchmarks are transmission line theory, Mie scattering, and photonics.
Additionally, the COMSOL user community continuously provides even more benchmarks and experimental verifications for the RF Module. Many of these user submissions have been presented at the annual COMSOL Conference, making them available free of charge on the COMSOL Conference CD. The conference CD can be ordered online at http://www.comsol.com/conference/cd/.
Multiphysics and Microwave Simulations
Earlier editions of the RF Module tutorial package came with a number of multiphysics and microwave simulation examples such as microwave heating of food and the mechanical deformation of microstrip filters. In fact, COMSOL has been developing multiphysics technology for electromagnetic wave simulations for more than 15 years.
“Users rely on us to provide the most versatile and integrated solution on the market for these strongly coupled physics phenomena,” says Magnus Olsson, PhD, product manager for electromagnetics with COMSOL. “We bring together microwave, heat, flow, and mechanical simulations.”
“One of the most significant multiphysics capabilities we provide microwave engineers is the ability to combine frequency-domain and time-domain simulations, such as the turning on-and-off of a microwave source, and solve for the transient heating with temperature-dependent material properties simultaneously,” Dr. Olsson adds.
