2. Computer-aided design (CAD)
The quest for ever more efficient hybrid or integrated microwave circuits is leading to ever greater complexity for the designer. Indeed, the grouping of multiple functions on a single small circuit makes it essential to study the interactions between elements beforehand. As measurements inside a microwave circuit are difficult, only numerical simulation can provide the information needed for its dimensioning. These digital simulation techniques are grouped together under the name of CAD: they comprise the following logically interwoven steps:
initial definition of the circuit based on the specifications;
analysis of its operation using models of its elements and components;
comparison between calculated and desired performance ;
analysis...

It would take a long time to compile a list of electromagnetic calculation software that could be useful for characterizing guides, discontinuities or systems. For some time now, however, a website has been available (although its continuity cannot be guaranteed) which provides a fairly comprehensive list of the main commercial and laboratory software packages:
