In this letter, we present the design, fabrication, and characterization of a 3-D photonic crystal (PhC) waveguide based on an optimized woodpile structure operating in the millimeter-wave band. By carefully adjusting the size and shape of the air defect, a silicon electromagnetic bandgap (EBG) woodpile waveguide can be created: this dielectric waveguide supports a well-confined TE10-like mode. Numerical results for this structure have been obtained using the finite element method (FEM) simulation software Ansys HFSS and present very good agreement with the measured ones.

Abstract
In this letter, we present the design, fabrication, and characterization of a 3-D photonic crystal (PhC) waveguide based on an optimized woodpile structure operating in the millimeter-wave band. By carefully adjusting the size and shape of the air defect, a silicon electromagnetic bandgap (EBG) woodpile waveguide can be created: this dielectric waveguide supports a well-confined TE10-like mode. Numerical results for this structure have been obtained using the finite element method (FEM) simulation software Ansys HFSS and present very good agreement with the measured ones.File in questo prodotto:
