Automatic Generation and Substitution of Placeholders for a MATLAB-HFSS Interface

The process of connecting full-wave simulators with numeric computing environments is typically done using application programming interfaces. These interfaces involve replacing the variables in the project file with placeholders, which can be a challenging task for designs with numerous variables. This paper demonstrates a method for automatically generating and replacing these placeholders. The interface between MATLAB and HFSS is used as an example, and it is applied to analyze a patch antenna.
