Diplexer design using EM and circuit simulation techniques

This article investigates a diplexer design technique utilizing the strengths of both EM- and circuit-based simulators to provide accurate results with reduced computation times. The EM circuit cosimulation technique effectively reduces the overall design time in passive component design, while achieving accurate results. This method can be extended to other passive component designs, such as comb-line filter and dielectric resonator filter, with a higher-order mode waveport calculation
