Using HyperStudy with Feko to Optimise a Bandpass Filter

Design a bandpass coupled line filter with HyperStudy as optimisation engine and Feko as the computational solver.

The design aims to obtain the best spacings for S1 - S3 in the depiction of the geometry below. The spacings are optimised to maximize the coupling between the input and output ports within the operating frequency range.

Note: The parametric model is provided for convenience. For the sake of simplicity, the cutoff frequencies and out-of-band performance will not be considered for the design.
