“…The curve corresponding to the experimental values shows that the inductance decreases with the increase of the frequency. This decrease is expected because in reality, the permeability of magnetic material decreases when the frequency increases [10]. But the simulated inductance remains practically constant versus frequency up to 0.9 GHz.…”

This paper presents the conception, fabrication and characterization of integrated inductors containing magnetic layers. We require different steps of micro-technologies: preparation of glass and ferrite substrates, RF sputtering, photolithography, etching and finally electroplating techniques for copper and gold films. The geometrical magnitudes are determined by using HFSS simulator software. The measurements performed at low and high frequencies (up to 1 GHz) permit to verify the correlation between experiment and simulation results. The inductance of the manufactured spiral inductor is about 200 nH and it is constant from low frequency up to 0.9 GHz.

“…Same results are observed for thin magnetic films, but the decreasing of the measured inductance is less noticeable. However, the simulated values of the inductance remain practically constant because the permeability is maintained constant during the simulation for all frequencies [25]. By comparing results obtained for thin and thick magnetic layers with the inductance without magnetic material ( fig.…”

This paper presents two fabrication techniques of spiral integrated inductors based on magnetic materials. For the first one, the magnetic core is a thin film deposited by RF magnetron sputtering, for the second technique the magnetic core is a thick layer of YIG obtained by micromachining. The addition of the magnetic material is expected to improve the performances of the integrated structure with electromagnetic shield. Low and high frequency equipment are used to characterize the manufactured components. A good correlation is obtained between the results by simulation and measurements for the two manufacturing techniques. These results show that the inductance increases when the thickness of the magnetic layer increases, we can double the inductance value for a thickness sufficiently high.

“…Sin embargo, presenta varias desventajas, entre ellas la pérdida del sentido físico de las variables que hacen que un diseño y no otro sea el óptimo. Debido a esto, se hace muy difícil comparar el diseño óptimo conseguido, con otros diseños que son similares, aunque no se consideren óptimos desde el punto de vista de las variables elegidas, pero que podrían presentar ventajas adicionales, no consideradas en las funciones de coste, tales como una menor complejidad del diseño o un menor coste [56]. Otra desventaja de la aproximación numérica proviene de la complejidad de las ecuaciones utilizadas y de la enorme cantidad de datos generados al resolverlas para cada combinación de parámetros.…”

A todos mis compañeros, por haber hecho no sólo soportable, sino disfrutable, el camino. A los compañeros del máster, especialmente a Carlos, por convertir Madrid en el punto de unión entre dos tierras castellanas. A los compañeros del despacho, tanto a los que ya no están entre nosotros como a los que, por desgracia, aún no han podido irse. A los compañeros del grupo de óptica, que creen que pW significa poderosísimos vatios.A mis colegas irlandeses, en especial a Ruaidhrí, que añadieron a mi dificultad para memorizar nombres la dificultad para escribirlos.A los técnicos del departamento. Especialmente a little Jesus, por enseñarme a soldar, y a big Jesus, por enseñarme a resoldar.A mis tutores. A Pablo por haber iniciado esto y a Cristina por haberlo terminado.A mis padres, que creyeron que estaba eligiendo una vida monacal y tuvieron que lidiar con la apostasía.A Alba, por haber encontrado a un ingeniero tan guapo, tan alto, tan inteligente y tan divertido, y aún así haberse quedado conmigo. Sigues siendo la mejor parte de mí, que soy tu peor parte.
