DESCRIPTION:The shooting and bouncing rays (SBR) method extends back to the
  1980s as an asymptotic technique for solving RCS and installed antenna pr
 oblems on electrically large structures. In this presentation\, SBR is und
 erstood to be a technique where geometrical optics (GO) rays are launched 
 from a radiation source to a scattering object\, and these rays are used t
 o “paint” physical optics (PO) currents on the target. The scattered f
 ield is determined by radiating the currents. SBR can be summarized as an 
 efficient technique for extending PO to multiple bounces using GO ray trac
 ing.\n\nAn important limitation of traditional SBR is its exclusive relian
 ce on GO as the mechanism for capturing interaction effects between differ
 ent parts of the scatterer. However\, a more general understanding SBR\, w
 hich we distinguish as SBR+\, allows the full array of well-established UT
 D techniques\, such as edge diffraction and creeping wave rays\, to be dep
 loyed to model interactions within the scatterer. That is\, any legitimate
  UTD ray path can be used to paint PO-like equivalent currents\, not just 
 the GO rays at the foundation of a UTD solution. This is particularly impo
 rtant where regions of the scattering geometry in the shadow of GO rays ha
 ve surface currents that create significant field contributions to a regio
 n’s observation points or angles.\n\nThis presentation focuses on the im
 plementation of SBR+ and its integration with ANSYS HFSS\, including these
  enhancements that help allow SBR to reach its full potential. Numeric exa
 mples are presented based on ANSYS HFSS and Savant commercial packages for
  installed antenna performance and RCS prediction.\n\nCo-sponsored by: Dep

 d extends back to the 1980s as an asymptotic technique for solving RCS and
  installed antenna problems on electrically large structures. In this pres
 entation\, SBR is understood to be a technique where geometrical optics (G
 O) rays are launched from a radiation source to a scattering object\, and 
 these rays are used to &ldquo\;paint&rdquo\; physical optics (PO) currents
  on the target. The scattered field is determined by radiating the current
 s. SBR can be summarized as an efficient technique for extending PO to mul
 tiple bounces using GO ray tracing.</p>\n<p>An important limitation of tra
 ditional SBR is its exclusive reliance on GO as the mechanism for capturin
 g interaction effects between different parts of the scatterer.&nbsp\; How
 ever\, a more general understanding SBR\, which we distinguish as SBR+\, a
 llows the full array of well-established UTD techniques\, such as edge dif
 fraction and creeping wave rays\, to be deployed to model interactions wit

 tering geometry in the shadow of GO rays have surface currents that create
