Abstract
A rectangular waveguide band-stop
filter using electromagnetic crystals (EMXT) surface as the top and bottom
walls is presented in this letter. The EMXT surface has a band gap that can
prevent electromagnetic wave from propagating along the waveguide. Dispersion
properties of the waveguide filter are analyzed using an approximated
lumped-element circuit model. A W-band prototype based on the proposed
waveguide filter is designed and characterized. The experimental results show a
rejection band centered at 97 GHz and a rejection level of 16 dB.
