June 3, 2020 8:30 AM - 4:00 PM EDT

View All COMSOL Day Locations

Join us for a full-day event with a special focus on microwave and optics simulations. You will have the opportunity to meet with COMSOL technical staff and customers, engage in product demonstrations, and gain insight into upcoming projects and focuses within high-frequency electromagnetics research and industry. Topics include the analysis of microwave, photonics, and optical components, including waveguides, antennas, lenses, and high-power laser systems. We will also address multiscale modeling and the coupling of electromagnetics simulations to other physics, such as heat transfer and structural mechanics, including RF heating and STOP analysis.

8:50 a.m.

Please join us 10 minutes before the presentation starts to settle in and make sure that your audio and visual capabilities are working.

9:00 a.m.

To start, we will briefly discuss the format of the day and go over the logistics for using GoToMeeting.

9:05 a.m.

See how you can deploy the power of high-fidelity simulation to engineers, designers, operators, and scientists throughout your organization.

9:30 a.m.

In this session, we will discuss the capabilities of the RF Module, Wave Optics Module, and Ray Optics Module for modeling Maxwell's equations in the high-frequency regime. We will discuss the different multiphysics couplings available for use, as well as case studies including radio wave, microwave, terahertz wave, and light propagation.

10:15 a.m.
10:30 a.m.
Parallel Sessions
Microwave and mmWave Applications

In this session, we will discuss how to efficiently set up and simulate RF, microwave, and millimeter-wave circuit and antenna models. Learn how to include just enough detail in a simulation model to accurately represent your design, while excluding parts that unnecessarily increase the computational cost.

Tech Café: Ray Optics

Join this Tech Café to discuss your applications based on ray optics as well as the modeling of the phenomena in general. Engineers from COMSOL will be able to answer your questions about simulating such phenomena and best practices when modeling them. Fellow attendees are also free to contribute their solutions, advice, and observations about simulating ray optics.

11:15 a.m.
11:30 a.m.
Parallel Sessions
Wave Optics for Photonics

We will present an overview of the Wave Optics Module, an add-on to COMSOL Multiphysics®. This module solves the Maxwell equations to simulate an optical wave’s propagations, reflections, refractions, absorptions, scatterings, diffractions, and all other optical phenomena in spaces that are comparable to the wavelength. Potential applications for this software are general optical components, including lenses, polarizers, prisms, gratings, beam splitters, fibers, waveguides, and photonic crystals. Other uses include devices such as lasers, laser diodes, LEDs, and superluminescent LEDs; as well as some special materials, including metamaterials, nonlinear materials, and anisotropic materials.

Tech Café: Microwave Heating

Being able to model multiphysics phenomena, where multiple types of physics influence each other, is prevalent in applications subject to microwave heating. This Tech Café will bring together COMSOL engineers and your colleagues in the industry to discuss how such phenomena can be best simulated and within which applications it is necessary and applicable.

Optical Modeling of Dielectric Metasurfaces

COMSOL’s Wave Optics Module offers an intuitive platform for designing dielectric metasurfaces and analyzing their optical properties. This presentation will discuss how TelAztec, LLC implements the Wave Optics Module into the research and development of passive metasurface designs, including antireflective surfaces and optical filters based on periodic arrays of nanoresonators. The finite element approach in COMSOL® fosters a deeper understanding of experimental results when characterizing metasurfaces after fabrication, allowing for the iteration of models to match real-life measurements. By employing sweeps of unit-cell geometry parameters, COMSOL® can rapidly generate critical information such as complex tolerances in the design and fabrication of dielectric metasurfaces.

1:45 p.m.
2:00 p.m.
Parallel Sessions
STOP Analysis

In this session, you will learn how to perform structural-thermal-optical performance (STOP) analyses using COMSOL Multiphysics®. Just as COMSOL Multiphysics® is able to seamlessly combine different physical phenomena, it can also combine different numerical methods. A typical STOP model involves heat transfer and structural mechanics modeling with the finite element method (FEM) and ray optics simulation.

Tech Café: Antennas

5G and SatCom application networks will soon be taking telecommunications to a higher level. They will require new devices to achieve this, all of which must be designed and optimized to meet this market’s needs. This Tech Café will discuss the challenges facing this new technology and how COMSOL Multiphysics® can best be used to achieve this.

2:45 p.m.
3:00 p.m.

There are many different approaches to modeling electromagnetic wave propagation, each with unique strengths and weaknesses. An approach like the finite element method (FEM) can solve Maxwell’s equations accurately, but requires a mesh that is fine enough to resolve individual wavelengths. A ray optics approach, on the other hand, requires several simplifying assumptions, but can be used in very optically large geometries. In this session, we will discuss how to choose the right tool for electromagnetics modeling, and how to combine these different tools in high-fidelity multiscale models.

3:45 p.m.
