EM.CUBE™ stands for Electro-Magnetic Collaborative Userware By EMAG. Its core functionality utilizes a modular approach to the solution of large-scale electromagnetic problems. EM.CUBE features a number of computational modules built upon a common framework that work together seamlessly to provide practical solutions to system-level RF problems.

EM.CUBE's core architecture consists of a tightly integrated suite of modules that are capable of modeling electromagnetic problems with utmost accuracy and efficiency. Each computational module has been optimized to address a certain class of electromagnetic structures based on a particular numerical technique. These highly customizable modules work together seamlessly providing practical solutions to real world system-level RF problems.

EM.CUBE's universal framework provides the ideal environment for hybrid simulations of complex, multi-scale electromagnetic problems, where a single numerical technique often proves to be computationally inefficient or simply impractical. In such cases, one usually breaks up a large structure into a number of smaller manageable sub-structures with common length scales or similar physical characteristics. Each sub-structures can be analyzed in EM.CUBE using the most effective simulation engine. The simulation results from different sub-structures can then be interfaced with each other using a number of cross-module utilities to arrive at the final solution.

The integration of EMAG's older products within EM.CUBE's unified and streamlined framework has been more of a necessity than a mere convenience. In the last fifteen years, EMAG Technologies has got involved in a large number of projects that required complex hybrid simulation tools for modeling multi-scale RF problems. Examples of these are co-site interference among tactical vehicular communication systems, adaptive networking in high multi-path urban environments, networks of unattended sensors with near-ground operation, antennas on engineered meta-material substrates or complex platform structures, and see-through wall imaging radar systems, to name a few. With the introduction of EM.CUBE, we hope to bring a totally new level of simulation capability to the desktops of user like you at a very low cost.

FDTD.module is a time domain FDTD simulator (with optional hardware acceleration) for full-wave EM simulation of 3-D structures, circuits, and antennas.

EM.CUBE's fdtd.module is the evolution of EMAG's former EMLOUNGE product, which was originally developed in 2005 for the U.S. Navy for modeling EMC/EMI and shielding effectiveness in electronic equipment. EMLOUNGE was later extended to handle complex 3-D antenna structures and mounting platforms. As EM.CUBE's fdtd.module, the tool can analyze a wide range of 3-D electromagnetic radiation, scattering and propagation problems. It also features an integrated SPICE-based circuit simulator, which together with the FDTD kernel can solve mixed circuit-EM modeling problems in a self-consistent manner. 

New features for 2009 include:

  • Simple RLC Lumped Elements
  • Linear or Nonlinear Active Lumped Circuits Defined by Netlist Files
  • Conductive Sheet Surfaces



PROP.module features an asymptotic SBR simulator for physics-based, site specific modeling of radio wave propagation.

EMAG's popular EMTerrano product, first introduced in 2003, reemerged as EM.CUBE's propagation.module. EMTerrano was originally developed for the U.S. Army to model communication system connectivity in urban battlefield environments. Its simulation engine was extensively validated by the U.S. Army in a number of real-world urban scenarios, and its performance surpassed all the competition tools by large margins. In its reincarnation as propagation.module, the older product is now equipped with a versatile and dynamic scene generator capable of treating arbitrary building geometries and interacts with EM.CUBE's full-wave analysis modules.

New features for 2009 include:

  • New Radiator Sets in Propagation Module: Define radiator sets consisting of multiple arrays and point radiators in arbitrary configurations and edit them individually or as a group
  • Arbitrary Block Geometries: The SBR mesh generator converts arbitrary objects to polygonal prismatic block with user-defined edge length and slice height.
  • Standard Material Interfaces vs. User-Defined Macromodels for Reflection and Transmission Coefficients at Blocks and Terrain
