SEMCAD Matterhorn V15.6 Released

With this new release, SPEAG delivers significant new improvements and capabilities to address a variety of engineering challenges in a wide range of applications, including safety assessment, EMI/EMC, antenna design, and dosimetry. Of particular interest are enhancements for exposure assessment of wireless power transfer (WPT) systems, analysis and optimization of in- and on-body wireless devices, and the simulation of 5G wireless systems.

Key new features of SEMCAD X Matterhorn V15.6 include:


  • A new lattice-based morphing engine allows for interactive morphing, with fast-rendering preview, of complex CAD objects like solids and meshes.
  • Productivity and framework enhancements comprise new modeling and alignment tools, for, e.g., plane clipping, camera settings, many Python scripting extensions, conversion of units; local modeling grids; calculators, e.g., for materials, and much more.
  • The Analysis and post-processing workflow has been streamlined and make accessing and quantifying the results more effective. For instance, we added various far-field extensions; an antenna array wizard; better markers for 2D plots; additional data importers/exporters and last but not least additional dosimetric averaging methods for assessing compliance with safety standards  such as IEEE 95-1 2005; ICNIRP 1998; ICNIRP 2010.
  • The necessary network tools for determination of S-parameters, fields, and port parameters have been improved to allow extraction of all results without resimulation.


  • The new Topological Voxeler allows better results to be achieved with coarser grids for discretization of complex structures with fine control of spacing and gap filling of fine gaps and holes, to result in a smaller grid and more than an order of magnitude faster runtime for specific structures.


    • In the P-EM-FDTD solve has been added Debye, Lorentz, Drude, and generic dispersion models (electric and magnetic) along with an improved dispersive parameter fitting tool, particularly useful for simulation of ferrites.
    • A bi-directional extension of the generalized Huygens approach in EM-FDTD has been added to allow, e.g-, incorporation of back-scattering and independent excitation of fields and remote objects.
  • EM LF
    • Various enhancements and extensions in the P-EM-LF module have been made, including multi-CPU/core and MPI parallelization.
  • Mode Matching
    • We added a new solver based on the mode matching technique for efficient and accurate simulation of passive waveguide structures, e.g., quasi-analytic computation of coupling between canonical waveguide cross-sections.
