Dispersion Characteristics of Fie Lines with Photonic Substrate

摘要

Current and foreseen applications of photonic crystals especially the PBG (Photonic Band Gap) can be divided according to their principle of functioning. In this work an efficient method is presented for the accurate full-wave analyses of the unilateral and bilateral finlines with a 2D PBG material as substrate. To analyze its efficiency, it's necessary to determine the phase, attenuation and effective dielectric constants. In order to analyze the behavior of the structure with this substrate, the full wave TTL (Transversal Transmission Line) method is used. Numerical results for the attenuation and effective dielectric constant of unilateral and bilateral finline with PBG substrate are presented.
