Abstract :
Scattering by dielectric posts in a rectangular waveguide is investigated by a combination of the finite and boundary element methods, and the equivalent circuits are derived. It is shown that some of the lossless dielectric post resonances in a rectangular waveguide can be physically realized by a lattice circuit, and the interaction between two posts can be evaluated by this circuit
