XFdtd 7.0 

XF7 has all the power, speed, and usability that our users have come to expect from our software, but with a simplified and ultra-modern architecture that is unprecedented in the market today.  

XStream Hardware FDTD uses the latest GPU Computing technology to provide dramatic speed increases in XFdtd calculation.  Utilizing the ability of the GPU (Graphics Processing Unit) in modern computer graphics cards to stream floating point calculations, XFdtd achieves extremely fast calculation speeds via the XStream Hardware FDTD option. XStream® Hardware FDTD is now based on the NVIDIA FX 5600 GPU with 1.5 GBytes of accelerated memory.  There are three versions of XStream 3.0 available from Remcom:  The basic XStream Single GPU with 1.5 GB of GPU memory for up to 50 Million FDTD cells fully-accelerated; the XStream MicroCluster consisting of Two XStream GPUs in a Quadro Plex 1000 chassis providing 3 GB of GPU memory for up to 100 Million FDTD cells fully-accelerated; and the XStream MiniCluster consisting of four XStream GPUs in two Quadro Plex 1000 chassis providing 6 GB of GPU memory for up to 200 Million FDTD Cells fully-accelerated.  XStream provides the calculation speed of a computer cluster at a fraction of the cost. 

Wireless InSite is an RF planning  tool for predicting the effects of buildings and terrain on the propagation of electromagnetic waves.  It major application is site-specific radio signal propagation prediction including effects of the locations of  transmitters and receivers within an urban area.  Physical  characteristics of rough terrain and urban structures are modeled, electromagnetic calculations are performed, and signal propagation characteristics are evaluated.  In addition to the basic ray-tracing capability, Wireless InSite can utilize the optional Moving Window and Urban Canyon FDTD propagation models.  Distinct from the ray-based methods, these models simulate propagation by directly solving Maxwell's equations using the Finite-Difference Time-Domain (FDTD) method. Moving Window FDTD is used to simulate propagation of radio waves at UHF and VHF frequencies over irregular terrain. Urban Canyon is intended for high-rise urban environments where the transmitting and receiving antennas are located close to the ground relative to building heights. Wireless InSite's innovative methods provide a powerful new tool in the hands of communication system design engineers.

XGtd is a general purpose ray-based electromagnetic analysis tool suitable for high frequency radiation, antenna, and EMC applications. XGtd combines GTD, UTD, and Surface Rays to include all important diffraction mechanisms present in high frequency analysis of devices in the vicinity of complicated objects. The software is aimed toward the analysis of antennas on vehicles or aircraft, but is also suitable for anechoic chamber simulations.  The powerful, user-friendly GUI is an efficient tool for importing CAD files of complex objects, setting up calculation parameters, running calculations, and viewing output. Antenna patterns generated by our full wave solver, XFdtd , or from NSMA can be imported into XGtd.  Output from the calculation engine includes near-zone fields, far-zone antenna patterns and antenna coupling and interference measures. Display of the possible ray paths, color-coded to indicate signal strength, is possible in addition to planar field displays of field strength.  If your application is too large for a full wave solver think first of XGtd.

VariPose

VariPose is a special purpose software tool that repositions the voxels of the Male Visible Human mesh including internal anatomical structures.  The body can be posed in realistic positions depending on the specific user application.  The repositioned meshes are  important in various bio-electromagnetic calculations including MRI, automotive, and body-worn communication devices including cell phones, wireless laptop, and blue tooth devices.   Starting with the Male Visible Human in 10, 5, 3, 2 or 1 mm voxel format, VariPose allows the user to reposition body joints from knee, hip and elbow down to thumb and finger joints. The actual repositioning process is computationally intensive and may take hours to days depending on the mesh voxel size and number of joints being repositioned. To make this efficient for the user VariPose consists of two modules, the Graphical User Interface and the Repositioning Engine. The GUI allows viewing of the original mesh and any subsequently repositioned mesh, and provides information on the meshes including number of voxels of each tissue type, change in mass by tissue type after repositioning, and both 3D and 2D visualization. The GUI also has a stick man skeleton which the user can manipulate in real time to control the repositioning of each joint. Once the user is satisfied with the new mesh position, the GUI writes a control file that is then read by the Repositioning Engine along with the original mesh. Once the Engine has repositioned the mesh, it can then be read into the GUI for evaluation. VariPose® will provide repositioned meshes in both XFdtd® and generic voxel formats.

Rotman Lens Designer

Rotman Lens Designer (RLD) software package is a tool for the design, synthesis, and analysis of Rotman Lenses and their variants. It is based on Geometrical Optics combined with the classical Rotman Lens design equations. It is intended for rapid development and analysis of Rotman Lenses given several physical and electrical input parameters. RLD generates the proper lens contours, transmission line geometry, absorptive port (dummy port) geometry, provides an approximate analysis of performance, and generates geometry files for import into Remcom's XFdtd® for further analysis and fabrication.
