Our starting point is developed by exploiting available empirical knowledge for SIW. We propose an efficient SIW surrogate model for direct EM design optimization in two stages: first optimizing the SIW width to achieve the specified low cutoff frequency, followed by the transition optimization to reduce reflections and extend the dominant mode bandwidth. Our procedure is illustrated by designing a SIW interconnect on a standard FR4-based substrate.engElectromagnetic Based OptimizationMicrostrip-to-SIW TransitionsSubstrate Integrated Waveguide (SIW)Substrate Integrated Waveguide (SIW)info:eu-repo/semantics/conferencePaper
