Significant Enhancements in CST MWS Asymptotic Solver
Engineers simulating electrically large structures, either for radar cross section analysis or for antenna placement studies, benefitted from the introduction of an asymptotic solver in CST MICROWAVE STUDIO version 2010. This solver is based on the shooting bouncing ray method. With the latest CST STUDIO SUITE 2010 service pack, significant functional enhancements have been made available to our customers.
The asymptotic solver can now use farfields as excitation sources. These farfields can be computed by other CST MWS solvers including the transient and frequency domain solvers. This makes the calculation of an installed antenna's farfield possible, even for an electrically very large structure such as a ship. Importing more than one farfield enables the computation of the coupling between several antennas, or of the total farfield including all antennas.
For scattering simulations, many excitation sources can be run in parallel. Their properties can be set by means of an excitation list. This enables the simulation of an arbitrarily polarized wave incident, or an incident from different directions. This is interesting in many radar applications.
"The development of an asymptotic solver for CST MICROWAVE STUDIO was in response to many requests from our customers who need to study structures that were, because of their electrical size, simply out of reach of the previously available solver set," stated David Johns, VP Technical Support & Engineering, CST of America. "The latest additions to the asymptotic solver represent a huge applicability increase in the area of antenna placement and RCS simulation."
