Savant

Savant is a sophisticated computational electromagnetic (CEM) tool for computing the installed performance of antennas as mounted on electrically large platforms.

• Predict installed antenna patterns and antenna-to-antenna coupling in complex environments.
• Optimized for electrically large, high-fidelity platforms.
• Intuitive and powerful user interface with 3D visualization for problem setup and results display.
• Multiple installed antennas defined by 3D free-space patterns or current distribution.
• General multi-layer materials for coatings, radomes and walls.
• Antenna siting for optimal performance and minimum cosite EMI, radome analysis.
• Complimentary capability to full-wave solver.
• Import 3D CAD models to define the platform/environment for Savant simulations.
• Define and place antennas interactively using 3-D free space radiation patterns or equivalent current sources.
• Single and swept frequency modes.
• Savant’s multi-core parallelized engine accounts for all important effects:
• Blockage, Diffraction, Multi-bounce
• Creeping waves
• Savant computes:
• Installed radiation patterns
• Coupling between Tx/Rx antenna pairs
• Spatial E & H field distribution
• Incident, scattered and total fields
• Specialized ray tools allow visualization of multi-bounce physics to gain a better understanding of the important interactions occurring.
• OS: Windows/Linux/Mac

Several powerful features in Savant make the tool easy-to-use and apply to the most challenging problems.

Savant Features:

• Sophisticated GUI for setting up, running and interpreting Savant simulation
• Support for a variety of CAD formats including ACAD Facet, Stereolithography, Wavefront OBJ, IGES, Gmsh, and IDEAS Universal.
• Library of parametrically defined antennas including common antenna types such as monopoles, dipoles, isotropic, hemitropic, directive beam, loop, etc.
• Support for representing free space antenna patterns as far-field radiation patterns or as current sources. Current source models are necessary when the antenna is electrically close to a surface.
• Free space antenna formats can be narrowband or wideband (ie. multi-frequency).
• Multi-layer material models for penetrable materials such as coatings, radomes and walls.
• Ability to compute far-field, near-field, and antenna-to-antenna coupling.
• Visual ray trace feature for aiding the analyst in understanding the ray interactions with the platform. Ray filter to specific far-field and near-field observation points supported.
• Physical Theory of Diffraction (PTD) wedge correction feature.
• Divergence factor correction included for curved surfaces (e.g., reflector antennas).
• Creeping Wave. Savant is the only commercially available SBR software with this feature.
• Smart power normalization feature.
• Multi-core support. The user can specify number of cores to use for a computation through the GUI.
• Dynamic zoning feature for major acceleration of computations involving many current sources.
• Extensive Help documentation including several tutorials.
• Advanced plotting capabilities including built in Cartesian and Polar plots with CAD overlay feature.

Savant is a product of Delcross Technologies. It can be purchased through CST distribution channels.
