  • Key strengths
  • Fidelity - Tetrahedral conformal mesh with
    quadratic surface
  • Accuracy - Higher-order finite elements (p 1-6)
  • Speed size - Massively parallel computing

Scattered field
  • Solve for defect mode using Omeg3P
  • Launch defect mode on PBG fiber port in T3P
  • Evaluate power flow of scattered field at far
    distance

B field
Defect mode driven here
Port Mode
Excitation of defect mode
  • Solve for port mode at a specified frequency
    using a 2D eigensolver
  • Load port modes onto coupler ports for S3P to
    determne scattering properties
