Foundations of Ray Tracing Methods in Electromagnetics
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 you 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.
