Modeprop

ModePROP

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 Maxwells 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

Applications

ModePROP has applications including, but not limited to:

ModePROP simulation results of a blazed finite surface grating. An incident Gaussian beam is coupled into a waveguide by a surface grating.

Key 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
• Increased performance through multi-threading and GPU acceleration on computers with multiple cores/CPUs and high-end graphics cards
• Accounts for reflections
• User-defined initial field
• Accommodates complex index for Iossy materials and high index contrast profiles
• Robust meshing scheme which conforms to the structure
• PML boundary conditions
• Output information includes transmission/reflection of individual modes as well as total values, and the Poynting Vector
• Sophisticated output options allow user to calculate and display field profiles and other electro-magnetic quantities at any position
• Automated parametric studies and design optimization using MOST (page 24)
