Cobham Technical Services has announced a new release of the Concerto electromagnetic design software for RF and microwave applications from its Vector Fields Software product line. The latest version — Concerto v7.5R1 — incorporates numerous updates to further design, simulation, and analysis.
Many of the updates in this release center on the 3D geometric modeler that is part of all Concerto configurations. This has new meshing options for the finite element (FE) Eigenvalue solver, and the modeler now provides access to a range of additional features in Concerto s finite difference time domain (FDTD) simulation engine. Among these is the ability to present frequency domain field plots over any regions of the model, and for any number of frequencies, from a single time domain analysis.
The modeler now also supports features for the simulation of complex materials in FDTD. One new feature allows the definition of lumped ports with frequency dispersive properties, based on the Drude, Debye and Lorentz models, providing a circuit element representation of discrete structures within complex materials. Support for the simulation of metamaterials has been updated by allowing their representation by bulk constitutive properties.
Concerto maintains its scripting capability, allowing automation of many features of model creation analysis and post processing. The latest release extends the range of commands and features in the scripting language, and provides a redesigned and enhanced editor for creating and editing command files.
Concerto provides an FDTD simulator as standard, enabling users to model a wide variety of microwave devices such as antennas, waveguides, filters, cavities and resonators. In addition, a Method of Moments (MoM) analysis module uses formulae for the analysis of arbitrary geometries. Typical applications include radar cross-section calculation and the evaluation of antenna performance and placement on aircraft and ships. For designers wishing to characterize the performance of devices such as RF cavities and microwave resonators, Concerto offers a Finite Element Method (FEM) analysis module, which determines the eigenvalues and associated eigenvectors of resonant structures.
