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

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
