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.

Before high-frequency and 5G-based high-speed communication systems can be developed and deployed, the performance of the devices used in these systems needs to be predicted. At the same time, analyzing and evaluating the performance of optical components for lasers, telescopes, and similar equipment and systems is necessary to model as part of the design process. In many cases, more than just the high-frequency electromagnetic behavior of these components needs to be considered, as they are invariably influenced by other physical phenomena, such as heat transfer and structural stresses.
During this session, the latest trend in modeling the behavior of microwave and optical components and applications will be investigated: You will learn how simulation specialists make their complex and high-fidelity multiphysics models available for other departments and for their customers.
Divide & Conquer: 3D Plasma Modeling for a CO2 Laser Using a Multilevel Approach
Modeling and numerical simulations are considered an indispensable part of product and process development at Coherent, as pushing the limits requires a thorough understanding of the underlying processes and their interplay.
High-power CO2 lasers are complex devices, and the challenges in current R&D work usually involve nonlinearities of different kinds. Furthermore, product development often requires dealing with multiple time and length scales as well as several strongly coupled physical phenomena at once, rendering straightforward numerical simulations infeasible in many cases. These multiscale and multiphysics problems can be handled with a reasonable amount of computational resources by partitioning the full problem into a hierarchy of manageable tasks similar to the “divide & conquer” paradigm in computer science.
For example, this approach enables a 3D model of a planar gas discharge in a CO2 laser involving RF and plasma physics, allowing to optimize homogeneity and stability. As a result, it is possible to identify further development potentials to optimize our current and future products.
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.
Get an introduction to the capabilities and fundamental modeling workflow of COMSOL Multiphysics®. You will see a live demonstration of the entire analysis process via a practical high-frequency electromagnetics example, and see how quick and easy it is to turn your sophisticated model into a specialized app that any engineer can use.
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.
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.
Interfacing 3D Near Fields with Optical System Design
As an expert in the classical design of imaging systems, Zeiss is more and more advancing to feature sizes where optical near-field and interference effects significantly impact the accuracy of a measurement process. As such, the need for accounting for these effects within the design process of more precise measurement systems is immense. I will present how interfacing classical optical systems with COMSOL Multiphysics® simulations can look like with three exemplary use cases.
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.
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.
Optimization makes it possible to find the best possible parameter settings, geometry dimensions, and material properties for antennas, waveguides, and optical systems. In this presentation, you will learn which optimization techniques are available in COMSOL Multiphysics® and how to use them to optimize your high-frequency electromagnetics devices.
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.
