Features

Optimized Simulation Engine

  • Contains proprietary algorithms that optimize use of computer memory and processor architecture.
  • Uses a graded mesh with auto-mesh technology to create the most advantageous mesh depending on the structure of interest and the desired accuracy.
  • Experimentally verified: "The simulation gives us the answers we need, and the results perfectly match what we measure in the laboratory." - B. Cunningham, CTO, SRU Biosystems

Intuitive 3D Layout Editor

  • Use the 3D CAD interface to draw micro- and nano-photonic structures easily, with top, side, end, and perspective views.
  • The tabbed interface provides an intuitive workflow for creating and running simulations and analyzing the resulting data.

Accurate and Flexible Materials Capabilities

  • Accurately describe optical structures that consist of any combination of dielectrics, semiconductors, and/or metals in arbitrary geometries; dispersive and anisotropic properties are also treated.
  • The built-in materials database includes several pre-defined materials as examples and to get started quickly.

Integrated Data Visualization and Analysis

  • The analysis window allows for quickly plotting and visualizing EM simulation data such as near field intensity profiles, vector field components, and power flow.
  • Movie Monitors allow viewing of light propagation in and scattering from the optical structures of interest.

Powerful Scripting Language

  • Simple and straightforward syntax is used in a high level programming language similar to MATLAB and C that includes “EM Toolbox” functions that provide the framework for in-depth analysis of any situation.
  • The scripting language is comprehensive, providing users with the ability to write scripts to control all aspects of setting up, running and analyzing simulations.

Built-in “EM Toolbox” Analysis Functions

  • FDTD Solutions contains a host of built-in functions that give users direct access to quantities of interest without having to worry about the details of the FDTD technique.
  • Quantities such as the source power spectrum, integrated power flux across any surface, and near-to-far field transformations are easily computed.

Hardware and Operating System Support

  • 32-bit and 64-bit Windows and Linux O/S.
  • Supports multi-core, multi-processor, and/or clustered computers systems.
