Photonic crystal waveguides at millimeter and submillimeter wave (2)

摘要

We have proposed a photonic crystal waveguide for millimeter and submillimeter wave on previous report. This waveguide, however, is not very low propagation loss because metallic loss and bending loss didn't decrease so small. We propose a new waveguide replaced metals to photonic crystals. The new waveguide decrease propagation loss to around 7 dB/m (tanδ=10{sup}(-4), λ=1 mm) compared with conventional waveguide including dielectric loss ～3 dB/m and metallic loss ～15 dB/m.
