CST MICROWAVE STUDIO® - Transient Solver

The Transient Solver of CST MICROWAVE STUDIO® (CST MWS) is a general purpose 3D EM simulator. Real time domain simulation is particularly interesting if you want to study the field propagating through a component or along the traces of a PCB. Time Domain Reflectrometry (TDR) comes naturally with such an solver, but also Signal Integrity (SI) applications benefit from the capability to use arbitrarily shaped time signals.

Besides the specific capabilites in time domain, the Transient Solver also delivers broadband frequency domain results like S-parameters. These simulations can be performed with an arbitrary fine frequency resolution without extra computational cost, thus avoid missing single resonances inside the spectrum. Field results for many frequencies (for example 100 farfield samples) can be derived from one single simulation run.

CST MWS can be easily distinguished from other time domain tools. Proprietory technologies suche as the PERFECT BOUNDARY APPROXIMATION (PBA)® (1998), the THIN SHEET TECHNIQUE (TST)™ (2001), and the MULTILEVEL SUBGRIDDING SCHEME™(2003) combine (and exceed) the memory efficiency and performance expected from time domain simulators with the excellent accuracy of conformal methods.
