About this Webinar

A broad class of electromagnetic (EM) problems involves objects and environments that span hundreds to thousands of wavelengths: installed antenna performance and coupling, indoor/outdoor RF propagation, inter-vehicle (V2V and V2X) communication, radar signatures and sensing, reflector and lens antennas. We've seen tremendous advances in full-wave EM solvers like finite element method (FEM), integral equation method (IE), and finite difference time domain (FDTD) that directly solve Maxwell's Equations. Increasing demands of memory and computing resources rapidly grow with increasing problem scale. They remain fundamentally bound by their requirement for sub-wavelength meshing and the need to either solve ever-larger matrices or propagate fields through billions or trillions of fields cells. These applications can't be practically solved at high frequencies using the best manifestations of these computational EM (CEM) techniques.

This webinar presents the latest techniques and capabilities of the shooting-and-bouncing rays (SBR) method, as manifested in HFSS SBR+.

What Attendees Will Learn

  • The foundations of shooting and bouncing rays (SBR) as a computational electromagnetic (CEM) methodology
  • How traditional SBR is extended in HFSS SBR+ to incorporate edge diffraction, creeping wave, and volumetric refraction mechanisms
  • How SBR relates to other CEM methods
  • Practical applications of HFSS SBR+
  • Massive acceleration of SBR+ using ray-based algorithms and GPUs to realize its full parallelization potential

Who should attend

Current HFSS users, novices to EM simulation, and any users of other EM solvers are all welcome to attend.

Speakers:

Bob Kipp

Dr. Robert Kippis a Distinguished Engineer with Ansys and currently leads its HFSS SBR+ development team. He received his Ph.D. in Electrical Engineering from the University of Washington in 1993. In the over 25 years since then and across four companies, Dr. Kipp has continuously focused on advancing the frontiers of shoot-and-bouncing rays (SBR) method, starting with his algorithm and coding work on the Xpatch radar signature tool. During this time, he 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. Dr. Kipp joined Ansys in 2015 with its acquisition of Delcross Technologies, the company he co-founded in 2006.
