A novel TEM waveguide using uniplanar compact photonic-bandgap (UC-PBG) structure

@article{citeulike:2776227, abstract = {A novel waveguide using a photonic bandgap (PBG) structure is presented. The PBG structure is a two-dimensional square lattice with each cell consisting of metal pads and four connecting lines, which are etched on a conductor-backed Duroid substrate.

A relatively uniform field distribution along the cross section has been measured at frequencies from 9.4 to 10.4 GHz.
