This work explores the possibilities of creating stop bands (or bandgaps) for TEM mode in parallel plate waveguides by using artificial surfaces in one of the plates. Particularly, as artificial surface a textured periodic surface made of metal pins has been selected. The present paper reports a parametric study of the "Fakir's bed of nails" structure in terms of the size of the achieved bandgap when the structure is placed within a parallel plate waveguide. Bandwidths larger than 2:1 are seen to be possible. The proposed structure could be used for the design of the new type of waveguides named gap waveguides.
