MODULAR 3D ELECTROMAGNETIC SIMULATION SUITE
      THAT GROWS WITH YOUR MODELING NEEDS

EM.Cube R18.1 At A Glance

The new EM.Cube R18.1 release is the most powerful electromagnetic simulation suite EMAG Technologies Inc. has ever produced in its history of more than two decades. The new release offers a combination of productivity features requested by our valued users as well as state-of-the-art simulation capabilities that reflect the latest advances in computational electromagnetics (CEM).

New EM.Tempo Features

• New gyrotropic materials including ferrites and magnetoplasmas
• New expression-based dielectric material properties defined as standard mathematical or Python functions of 3D spatial coordinates
• New way of defining voxel-based inhomogeneous dielectric materials using a Python function to retrieve data from a 3D Cartesian (voxel) database
• New arbitrarily oriented Hertzian short dipole sources compatible with EM.Cube's other computational modules
• Import of wire current solutions from EM.Libera as a set of Hertzian short dipole sources
• New wire (filamentary) current sources parallel to one of the principal axes with uniform, triangular or sinusoidal profiles
• Generalized lumped voltage sources with an arbitrary orientation on any PEC line object
• New series RL and parallel RC lumped devices
• Active one-port and two-port Netlist-based lumped circuits on PEC lines parallel to one of the principal axes
• Enhanced multi-frequency field sensor, radiation pattern, RCS and Huygens surface observables with data management options
• Computation of electric, magnetic and total energy density, dissipated power density, SAR density and complex Poynting vector on field sensor planes
• New volumetric field sensors
• 3D spatial Cartesian data visualization

New EM.Terrano Features

• New digital modulation schemes with 17 waveform types for computation of Eb/N0 and bit error rate (BER)
• Broadband frequency sweep of the propagation scene with uniformly spaced or discrete frequency samples using a single ray tracing simulation
• New option for using multi-frequency radiation patterns in frequency sweeps
• Complete polarimetric (theta-phi) characterization of the propagation channel for MIMO analysis
• New Polarimatrix solver using a ray database as an "almost real-time" alternative to physical ray tracing
• New transmitter sweep for modeling mobile transmitters
• New rotational sweep for modeling beam scanning
• New Mobile Path wizard and mobile sweep simulation of transmitter-receiver pairs

• New accelerated, multi-core-parallelized, full 3D SBR ray tracing simulation engine based on the k-d tree formalism with up to 5x speedup
• New native half-wave dipole radiators oriented along the X, Y or Z directions for defining standard transmitters and receivers
• New "Basic Link" wizard and new Python commands for quick creation of standard transmitters, receivers and Tx/Rx arrays
• New Global Environment dialog for defining the properties of the global ground in the lower half-space and global atmosphere in the upper half-space including absorptive atmosphere and global rain and fog conditions valid up to millimeter wave bands
• Frequency sweep using multi-frequency radiation patterns and pattern rotation sweep using a single SBR simulation run
• Ability to separate the effects of direct (LOS), reflected, transmitted and diffracted rays in the propagation analysis
• Ray tracing inside material media and penetrable volumes capturing refraction, attenuation and phase retardation effects
• Improved ray analysis and post-processing of each individual receiver including plots of angles of arrival and departure and power delay profiles

New Visual Interface

• New streamlined visual interface with a tabbed window shared between the Navigation Tree and Python Interpreter
• Persistent user customization of the visual interface - Most of your settings will be remembered the next time you open the application.
• A large collection of problem type templates driven from accessible Python scripts
• Generation of CAD report containing all the objects names and their basic properties

New Data Visualization, Plotting & Processing Utilities

• New Matlab-style 2D and 3D plot types including Cartesian, polar, colorgrid, contour, surface, etc.
• A large collection of Python scripts for custom plotting using PyPlot
• Tighter integration of EM.Cube data and Python
• Conversion of all simulation data to Python NumPy arrays for further post-processing by the user

Enhanced Python Capabilities

• More than 250 native Python commands for parameterized CAD modeling, simulation setup and simulation flow control
• More than 150 wizards and preloaded Python scripts for quick creation of transmission lines, antennas and propagation scenes, data processing and plotting
• User defined Python functions that can be used for parameterizing geometric objects, sources and other project attributes, defining dependent variables, custom output parameters and design objectives, or performing post-processing computations on the simulation data
• Improvement of CAD model export/import using Python scripts as a basis for building new wizards or reusable projects
• Running full-scale Python functions and executing scripts from the command line of Python Interpreter or from Models dialog
