New Features in XGtd version 2.5 

Performance Enhancements 

Improved run times for complex platforms and objects
The XGtd ray model now includes an optimized ray engine (ORE), which increases the speed of ray-tracing computations for problems that include complex objects, such as detailed vehicle models with large numbers of facets. Run-time benchmarks have demonstrated as much as a 2.5 time reduction in run time, depending on complexity (greatest improvement was for a 12,000-facet aircraft model). 

New 64-bit version
This new version of XGtd takes advantage of 64-bit systems, providing modest improvements to run-time (factor of 1.5 - 2 x reduction) and allowing for larger or more detailed facet models of objects. 

Multi-process tokens included in base price
Multi-process token licenses will now be offered in the base package, with support for up to 8 included in the base price.  

New Capabilities for Transmitters, Receivers, and Antenna Radiation 

Ability to create antenna arrays
An antenna array can now be created from the built-in antenna models by specifying the amplitude, phase, and geometric offsets for each element of the array. 

Trajectory transmitter/receiver sets
Users can now model transmitters or receivers along a trajectory using the new trajectory transmitter/receiver set type. Unlike other set types, the antenna orientation is relative to the orientation of each individual point in the set. 

Spherical transmitter/receiver sets
Transmitters or receivers can now be placed along the surface of a sphere allowing for spherical displays of field results around objects. 

New support for user defined 2-cut plane antennas
Users can now specify antenna radiation patterns using two perpendicular cut planes (nominally vertical and horizontal), which is the typical format provided by antenna vendors.  

Improvements to Graphical Displays 

Create multiple material plots in one step
All reflection and transmission coefficient plots in both vertical and horizontal polarization can be added to a single graph at the same time. 

Partition values displayed on scale bars
The scale bar has been improved to add information about the range of values that each color covers. 

Save 2D antenna cut plane plots in project graphs
2D cut plane plots created from 3D far-zone calculations and built-in antenna models can be added to graphs that are saved along with the project. Graphs will automatically update as new calculations are made.
