ModePROP Product Overview
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.

Benefits
- Incorporates advanced algorithm options that extend the basic RCWA to improve its robustness, efficiency, and user friendliness.
- Fully integrated into the RSoft CAD Environment.
Applications
ModePROP has applications including, but not limited to:
- Waveguide/Fiber-based systems
- Surface-normal grating couplers
- Plasmonic devices
- Sensors
- Filters
- Mode converters
- Photonic bandgap
- Computing coupling efficiency
Features
- Full-vectorial analysis for both Cartesian and cylindrical (azimuthally symmetric) structures in 2D and 3D.
- Modal Transmission Line (MTL) framework to ensure that the simulation is unconditionally stable.
- Accounts for reflections.
- User-defined initial field.
- Accommodates complex index for lossy materials and high index contrast profiles.
- Robust meshing scheme which conforms to the structure.
- PML boundary conditions.
- Output information includes field profiles for any component, transmission/reflection of individual modes as well as total values, and the Poynting Vector.
- Automated parametric studies and design optimization using MOST.
