© 2017 IEEE. This paper describes a design tool of high-order three dimensional (3-D) filters by means of 2-D and 3-D electromagnetic (EM) softwares and two space mappings. The first space mapping aligns the 3-D EM response with the 2-D EM response of a low-order 3-D filter. The second mapping performs a calibration of the first mapping. The high-order filter is optimized using the fast 2-D EM software. The design parameters of the high-order 3-D filter are directly obtained by means of the calibration equations. This design tool is applied to 3-D bandpass filters with increasing order in evanescent rectangular waveguide.
