Unidimensional artificial dielectric and metamaterial structures in planar circuit technology

Summary form only given. Artificial Dielectrics have attracted the attention of the microwave and photonics community since the late 1940s. In the late 80s, Photonic Bandgap structures were proposed in order to enhance laser source efficiency by inhibiting propagation of spontaneous emission. Due to the inherent scaling properties of inhomogeneous dielectric media, this gave rise to the extension of these structures in the microwave and millimeter wave band, with application to multiple devices and services. Later on, in the early 2000, metamaterial structures were physically implemented, in which anti-parallel phase and group velocity or negative index of refraction could be achieved. A great deal of work has been done since then, with a large amount of devices and applications proposed in the last decade, spanning from frequency selective surfaces, filters or antennas, among others.In this work, the research line initiated in the research group of Prof. Mario Sorolla at UPNA will be described. An evolution, from EBG structures, synthesis based planar transmission line and planar transmission metamaterial devices loaded with SRR and CSRR elements will be described. The results have enabled the implementation of devices such as filters, couplers, antennas or delay lines, which find application in areas such as wireless communication systems, security or satellite communications.
