| Marco del Evento: |
In recent years there has been significant research on synthesizing new materials that can enable new and better antennas. These metamaterials are designed by making use of periodic structures, and often it is the surface characteristics of them that are of interest, in particular in antenna design. Special attention has been given to designing surfaces with high surface impedance in order to obtain an artificial magnetic conductor. These surfaces turn out to have frequency bands (bandgaps) inside which no surface waves can propagate along the surface, and they are therefore also referred to as electromagnetic band gap (EBG) surfaces. This "stop" characteristic of the EBG surface make it similar to the transversely corrugated surface that already in 1987 was the basis for introducing a concept of soft and hard surfaces, based on a terminology used in acoustics and diffraction theory. The EBG surface is equivalent to a soft surface. During 2006 metamaterials were used to design RF cloaks for making objects invisible to EM waves. The invention got attention in media due to the pictorial resemblace with Harry Potter's cloack. Similar cloaks were realized already in 1996 by making use of the "go" characteristics of the hard surface. During this course the background and theory of ideal magnetic conductors and soft and hard surfaces will be explained, as well as how to implement these theoretical models in existing software based on different numerical methods. The course covers also how magnetic conductors and soft and hard surfaces can be designed and practically realized, and how to analyze them without having to model each detail of the periodic structure. The limitations of the different analysis models as well as of the surface realizations themselves will be discussed with particular attention to diffraction effects, dispersion, surface waves, leaky waves, local quasi-TEM gap waves and bandgap properties. The work will be presented in relation to specific applications such as: ground planes, low-profile antennas, miniaturization, reduction coupling, removal of parallel-plate noise in multilayer circuit boards, gap waveguides for millimetre waves, waveguide slot arrays, packaging for microstrip circuits, reduction of far out sidelobes, directivity enhancement, high-efficiency hard horns, quasi-TEM waveguides, compact horn antennas, reduction of blockage from cylindrical objects, grid amplifiers and infinite array simulators. The last two days will be devoted to gap waveguides of different types
