Analysis of electrically large slotted waveguide array using high-order MoM

This paper focuses on the simulation of electrically large slotted waveguide array using accurate method. The main challenges are the lack of matched terminators and the enormous time and memory space consumption. Mode match method is used to construct the matched terminators, while the parallel high-order MoM is chosen to extend the capacity of MoM. Finally, a Ka-band waveguide array with 2068 narrow-wall slots is solved on a high-performance cluster.
