Experimental waveguides, bends and power dividers in the woodpile electromagnetic bandgap (EBG) material at Ku-band are demonstrated. Prototypes are fabricated from alumina, and use an efficient waveguide transition to enable high quality measurements. Low-loss transmission is demonstrated for a waveguide and a 90° bend, and near equal power division shown for a woodpile EBG waveguide power divider. The components have the potential to be scaled for applications at millimetre-wave and terahertz frequencies.
