“…Moreover, while the stop-band between the first and second modes is suppressed in glide-symmetric structures, a wide stop-band can be created between the second and third modes. This stop-band can be used to design low-cost gap waveguides [22][23][24] and low-cost contact-less waveguide flanges for millimeter wave measurements [25]. Due to the beneficial properties of glide symmetry, several methods for fast calculation of the dispersion characteristics of glidesymmetric structures (Cartesian and polar) have been presented [8,[26][27][28].…”

In this article, we provide an overview of the current state of the research in the area of twist symmetry. This symmetry is obtained by introducing multiple periods into the unit cell of a periodic structure through a rotation of consecutive periodic deformations around a symmetry axis. Attractive properties such as significantly reduced frequency dispersion and increased optical density, compared to purely periodic structures, are observed. The direct link between the symmetry order and these properties is illustrated through numerical simulations. Moreover, polar glide symmetry is introduced, and is shown to provide even further control of the dispersion properties of periodic structures, especially when combined with twist symmetry. Twist symmetries can, with benefit, be employed in the development of devices for future communication networks and space applications, where fully metallic structures with accurate control of the dispersion properties are desired.

“…The proposed EBG structure is only made of holes, which makes the manufacturing process easier with respect to the nails in gap waveguide technology. Among the advantages highlighted in [205], the higher accuracy and lower cost of manufacturing at high frequencies stand out. This technology represents a good alternative to GW as described in [206], though glide-symmetric structures are in general more bulkier.…”

Just when you think you know all the answers, the universe changes all the questions." iv a todo el mundo. En cualquier minuto y siempre sin un pero. Es un placer haber viajado contigo, compartido aventuras en Londres, Paris, Boston...y haber aprendido tanto de ti. También a Nora y María, las chicas de la sala del GRE. Vosotras sois parte imprescindible de este trabajo, hemos crecido juntos. Muchas gracias por todos los momentos de distensión, las risas, por apoyarme con la tesis y también con el teatro.Mariano, Eva, Vicent M., Marta, Lorenzo, Juan, Felipe. Conoceros aún más y aprender de vosotros ha sido un privilegio. Gracias, además, por haberme permitido compartir docencia con vosotros. Han sido momentos para crecer tanto profesional como vitalmente.Gente que va y viene. Que de algún modo siempre está. Marc, Cristina, Alexia, Jaime, por supuesto Toni B. y Tomás. Que suerte haberos conocido y que pena no haber compartido más tiempo. Sois personas brillantes y con mucha luz, ojalá pudiera robaros algo de ese magnetismo que transmitís, y ojalá, de la manera que sea, volvamos a encontrarnos. A la familia de Ecuador: Fernando, Diana, Carlos, Daniel, Anibal. A la de Marruecos: Zakaria, Hamza, Yousra. A la de Argentina: Juan Pablo, Alberto, Guillermo y tantos otros que seguro que olvido. También parte de este trabajo ha sido posible gracias a Ashraf, Jian, Abbas, Sadegh y Jin Lin, que fueron un apoyo fundamental durante mi estancia en Chalmers University of Technology. A mi familia. A mis abuelos Rosita y Miguel, Amparo y Salvador. Sé que habéis estado conmigo.A mi hermana Nuria, por aguantar mil cenas oyéndonos hablar de Antenas.A mi madre, por apoyarme y espolearme. Por exigirme siempre más cuando yo creo que es suficiente.A mi padre, por ser un guía infatigable, porque llegar hasta aquí a tu lado es de las mejores cosas que haré en esta vida.A Dulce, la mujer más extraordinaria del mundo. Si existe el destino, hizo bien al ponernos juntos. Tu a mi lado y yo al tuyo para superar todos los obstáculos y superar todas las barreras. Nunca habrá suficientes gracias por haberme apoyado tanto y haber sido tan paciente y sincera en cada etapa de este viaje.Es curioso como al final de todo, de tanto trabajo, debería sentirme inmensamente feliz, pero echando la vista atrás, no soy más feliz ahora que durante todo el camino recorrido a vuestro lado. Gracias.x
