The coupling matrix synthesis technique is used to design a 6-pole Chebyshev filter. In addi-tion, an artificial neural network is applied to provide the filter geometries using the desired frequency response. The optimized filter is fabricated by the computer numeric controlled milling pro-cess. The measurement results show that the insertion loss is less than 3 dB and the return loss is better than 17 dB in the range 276–310 GHz.artificial neural networkterahertzwaveguide bandpass filterjournal article10.3390/mi130608412-s2.0-85131368575
