MATHEMATICS, SIMULATION AND MODELLING

Cobham Technical Services
Cobham Technical Services has released Concerto v7.5R1, the latest iteration of its electromagnetic design software for RF and microwave applications from its Vector Fields Software product line.
Concerto provides developers with a cost-effective means of achieving the best solution in the shortest possible time. The latest version incorporates numerous enhancements to accelerate further every aspect of design, simulation, analysis and optimisation.
Many of the enhancements in this release centre on the powerful 3D geometric Modeller that forms an integral part of all Concerto configurations. This has new meshing options for the finite element (FE) Eigenvalue solver, which can result in significantly shorter solution times, and the Modeller 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 Modeller now also supports features for the efficient simulation of complex materials in FDTD. One new facility 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.
