The A Solver can simulate extremely large platforms such as aircraft, ships and buildings very efficiently, making it well suited to many kinds of antenna placement scenarios.Įlectromagnetic interference between subsystems, such as antennas on a platform or channels on a PCB, is a vital consideration in many applications. The ray-tracing Asymptotic Solver (A Solver) in CST STUDIO SUITE can now directly calculate the coupling between antennas. CST STUDIO SUITE 2017 expands this capability to extremely large platforms as well. On smaller platforms, the CST® Time Domain Solver and Integral Equation Solver are efficient options for antenna coupling simulation. System integrators and electromagnetic compatibility (EMC) engineers often need to know how antennas on a shared platform couple to each other. An example is shown in Figure 1.įigure 1 Multimode cavity filter design using Filter Designer 3D (a) and field plot (b). Filter Designer 3D can calculate the coupling matrix on which the filter engineer can base a design, or produce a full filter model that can be used as the basis of an optimization or system simulation using the full-wave 3D solvers of CST STUDIO SUITE. Filter Designer 3D can automatically synthesize cross-coupled and diplexer filter designs to meet the specifications, including transmission zeroes, Q-factor and equiripple. However, the complex and sensitive nature of these filters makes them challenging to design with traditional methods. These features include both front-end and back-end improvements across the suite, with many focusing on tools for synthesizing and simulating components, as well as for managing and analyzing these components as systems.Ĭross-coupled filters offer a compact and high-performance way to use the spectrum efficiently. CST STUDIO SUITE® 2017, the upcoming* release of the EM and multiphysics simulation package, introduces new features that extend the software’s range of applications. EM simulation reduces costs and design time, enabling users to analyze and improve the performance and compliance of components and systems from the earliest stages of design.
