Description
Summary:An experimental study of eigenwaves is carried out for EBG waveguides: axial three-row, diagonal five-row, and coupled three-row waveguides based on an electromagnetic crystal that represents an array of circular metal cylinders located inside a planar waveguide. The frequency dependence of the slowing factor of an eigenwave is measured using a resonator technique that employs measurement of the resonance frequencies of a resonator (a short-circuited fragment of an EBG waveguide). Electrodynamic simulation of resonators based on EBG waveguides is carried out. The measured slowing factors are compared with the data obtained using electrodynamic simulation of short-circuited EBG resonators and resonators with periodic boundary conditions. The experimental results are in good agreement with the calculated data.
