Application of Photonic Material in Unilateral and Bilateral Finlines

The objective of this work is to use PBG (Photonic Band Gap) material in the unilateral and bilateral finlines. To analyze its efficiency, it’s necessary to determine the phase, attenuation and effective dielectric constants. To analyze the behavior of the finline with this substrate, the full wave TTL (Transversal Transmission Line) method is used. New numerical results for the attenuation and effective dielectric constant of unilateral and bilateral finline with PBG substrate are presented. A good agreement in comparison to other works is obtained.
