Electromagnetics Foundation Webinar Series

This 5-part webinar series describes Ansys Electromagnetic Simulation technology in detail and discusses the 30 year history of Computational Electromagnetics and its incorporation into Ansys EM solver technology. Users of Ansys EM tools & solvers will gain a more profound understanding of how Ansys EM simulation technology functions ‘under the hood.’

This unique series will be presented by senior technologists at Ansys – Directors, research Fellows and principal developers of the Ansys computational electromagnetics products.

This webinar series covers the following topics:

Foundations of Computational Electromagnetics
Discover the different ways to express Maxwell's equations: integral-vs-differential, time-vs-frequency domain, and how these give rise to different types of solvers. You'll get an overview of different approaches used for these solvers and the trade-offs for choosing the best solution method. 

The presenter will be Ansys Fellow and Chief Technologist Dr. Eric Bracken. Part of Ansys since 1996, Dr. Bracken is specialized in signal and power integrity analysis, EMI/EMC, parasitic extraction, circuit simulation, and model-order reduction.  

An Overview of the Foundations of HFSS and Maxwell Solver Technologies
We'll provide the critical technologies overview for HFSS and Maxwell, plus the recent advanced features. The various numerical methods (finite elements, integral equations, etc.) included in HFSS and Maxwell will be discussed and positioned with solver options such as direct and iterative algebraic solvers.

Presenters for this webinar are Dr. Rickard Petersson and Dr. Ping Zhou.

Dr. Petersson is R&D Director at Ansys, Inc., is responsible for electromagnetic field solvers including specialized solvers for signal integrity. He has a broad background in electromagnetics with expertise both in computational methods and electromagnetic theory with several publications in these areas.

Dr. Zhou is a director of research and development in ANSYS, leading the research and development of low-frequency products.  He has published more than 90 papers in the area of electromagnetic numerical simulation and material modeling, especially for electrical machine applications. He joined Ansys in 1994 and is the original author of Ansys Maxwell. 

The Foundation of Domain Decomposition Technologies in HFSS
We'll begin with a theoretical overview of domain decomposition formulations in HFSS and dive into how HFSS solvers evolved over the past decade. In-depth, we'll discuss the various DDM technologies available in HFSS, including 3D component array, FE-BI/IE Region, and mesh fusion.

Dr. Kezhong Zao will be presenting this webinar. He joined Ansoft corporation in 2007, where he is currently a distinguished engineer leading the high frequency-signal integrity FEM solver team. Dr. Zao has made significant contribution to HFSS including work on the domain decomposition solver, finite array and 3D component array solver, FE-BI and hybrid regions, and the mesh fusion solver.

Learning Ray Tracing Methods Foundations for Electromagnetics
This presentation includes foundations of shooting and bouncing rays (SBR) as a computational electromagnetic (CEM) methodology. You'll learn how traditional SBR extends in HFSS SBR+ to incorporate edge diffraction, creeping wave, and volumetric refraction mechanisms. Plus, we'll share practical applications of HFSS SBR+ for various use cases.

Presenting this topic will be Dr. Robert Kipp, who is a Distinguished Engineer with Ansys and currently leads the Ansys HFSS SBR+ development team. Dr. Kipp has implemented numerous SBR solvers while leading teams developing commercial SBR software products, using these to solve diverse applications ranging across installed antenna performance, reflector antennas, indoor/outdoor radio wave propagation, EMI/EMC, radar signature prediction, antenna scattering, and automotive radar simulation.

The Foundation of Computational Optics and Photonics
Covering the basics of ray tracing, including sequential and non-sequential methods, surface and volume scattering models, we'll show temperature and stress-dependent effects. You'll see full-wave time and frequency domain electromagnetic solvers for optics and photonics and how to simulate quantum photonic effects.

The presenter for this webinar is Dr. James Pond, who was a co-founder and CTO of Lumerical and was a driving force behind the company’s core software algorithms, technology, and advanced photonic modeling capabilities. He has more than two decades of experience in optical and photonic simulation, and is the author of numerous papers, patents and conference presentations. Currently he is Principal Product Manager at Ansys where he continues to work on the core photonic technology, in addition to integrating Lumerical products into the Ansys portfolio.

The Foundations of the Ansys RaptorX Silicon-optimized Electromagnetic Solver

Focused on microchip-level electromagnetic issues, this webinar will explore the numerical methods and solving engines within the RaptorX solver. RaptorX was developed to model and simulate the complex electric and magnetic coupling effects manifesting themselves in today’s silicon, replete with mixed analog and digital circuit blocks & signaling, high bandwidth busses, gigahertz frequencies and multi-chip/stacked chip implementations.

The presenter is Dr. Kostas Nikellis, an Ansys R&D Director responsible for high speed and RF SoC silicon modeling. Dr. Nikellis is originally from Helic Inc., which he joined in 2002, and came to Ansys when the company was acquired by Ansys in 2019. He received his PhD in Electrical and Computer Engineering from the University of Athens in 2006.
