ModePROP is an eigenmode expansion propagation tool that accounts for both forward and backward propagation and radiation modes. It provides a rigorous steady-state solution to Maxwell's equations that is based on the highly-stable Modal Transmission Line Theory. A full array of analysis and simulation features make this tool flexible and easy to use.

Simulation results that show the field scattered by an air groove.

Benefits

• Rigorous full-vector analysis.
  
• Solves for both forward and backward traveling modes.
