COST-Action IC1102 - Versatile, Integrated, and Signal-aware Technologies for Antennas (VISTA)
Kurzbeschreibung
(Englisch)
Antennas, both as wireless sensors and as wireless transducers, are at the forefront of the supporting technologies required in the design of modern wireless systems. As antenna systems and environments become increasingly complex, highly sophisticated modeling techniques are coming into play. This is particularly true for most planar antennas, which generate their electromagnetic radiation embedded in multilayered and/or complex environments. Moreover, the antennas operate at higher and higher frequencies (Terahertz applications) and the new technologies call for the consideration of antenna 'non-classic' substrates (anisotropic biological tissues, plasmas and plasmonic materials, lossy semiconductors in integrated circuits, thin solar cells, tropical woods for sustainable antenna mass production in emerging countries, highly dispersive metamaterials...). Hence, there is a need to extend the classical numerical modelling tools to these situations. In the context of planar multilayered antennas, Integral Equation (IE) models are recognized as the faster and most accurate. This project will address the development of several algorithms needed for the generalisation of these IE models: 1) the construction and numerical calculation of the Green's functions associated to the new materials and environments and 2) the correct treatment of the singularities created by these GFs when the IE approach is discretized and implemented as a Method of Moments (Galerkin) code.

Abstract
(Englisch)
Antennas, both as wireless sensors and as wireless transducers, are at the forefront of the supporting technologies required in the design of modern wireless systems. As antenna systems and environments become increasingly complex, highly sophisticated modeling techniques are coming into play. This is particularly true for most planar antennas, which generate their electromagnetic radiation embedded in multilayered and/or complex environments. Moreover, the antennas operate at higher and higher frequencies (Terahertz applications) and the new technologies call for the consideration of antenna 'non-classic' substrates (anisotropic biological tissues, plasmas and plasmonic materials like graphene, lossy semiconductors in integrated circuits, thin solar cells, tropical woods for sustainable antenna mass production in emerging countries, highly dispersive metamaterials...). To achieve proper mathematical modeling and a good engineering design of these antennas, the MoU of this COST Action IC1102 ('VISTA') considers that 'it becomes critical to be able to simplify the problems, accelerate the algorithms and make an optimum use of the processing resources available and memory'. The Swiss contribution to the Action, mainly include in this project will make a sizeable step forward in this direction. In the context of planar multilayered antennas, the best answer to to the questions raised in the MoU is provided by Integral Equation (IE) models, as explicitly mentioned in the approved Scientific Programme of the Action. In a previous COST Action (IC0603, two critical issues were identified for a proper development of IE models: 1) the construction and numerical calculation of the Green's functions associated to the new environments and 2) the correct treatment of the singularities arising in these GFs when the IE approach is discretized and implemented as a Method of Moments (Galerkin) code. These are the challenges that will be faced in this project. Particular emphasis will be put in the modeling of very thin conductive layers, like the semiconductor sandwiches forming the modern solar cells or the very promising graphene-based sheets with thickness of only a few molecules and on its behavior at THz frequencies and above.
