WebA cylindrical post is introduced into the broader side of the waveguide; it produces a similar effect as an iris in providing lumped capacitive/inductive reactance at that point. When a metalpost extends completely across the waveguide, parallel to an electric field, it adds an inductive susceptance that is parallel to the waveguide. WebAbstract. The waveguide is a hollow metal which has a function to transmit electromagnetic waves. This paper discusses a passive device of double – irises rectangular waveguide Band Pass Filter (BPF) with carried out simulation modeling. This BPF implemented with waveguide technology which the rectangular waveguide used is WR 284, with inductive
