Bandpass, lowpass, bandstop filter design — hairpin, coupled-line, combline, stub, SIW for frequency selection and harmonic rejection. TRIGGER: user asks to design, create, or analyze any RF filter (bandpass, lowpass, highpass, bandstop, hairpin, coupled-line, combline, stub, SIW). Invoke BEFORE writing code — filter class names differ from what you would guess. SKIP: EM simulation/S-parameter extraction of an existing filter (use matlab-analyze-em), general PCB layout assembly (use matlab-assem

One of 18 test cases the skill fixed. Same model, same prompt, with and without the skill.
Write a MATLAB function call to compute 2-port S-parameters for a PCB filter object f over 101 points from 1 GHz to 5 GHz using fast interpolating EM solver options.
