Design of an efficient 900 GHz antenna in standard CMOS technology for imaging arrays
No full textThis paper describes and addresses the challenges that are encountered while designing a 900 GHz antenna for FET detectors using a standard submicron CMOS technology. The reduced metal stack, the problem of surface waves and technology-related rules are taken into account in order to properly design an efficient antenna, with the objective to couple it to field-effect transistor (FET) detectors in a focal-plane array configuration. Simulations on a 0.15-μm standard CMOS technology show that up to 58% efficiency with responsivity in the several kV/W range can be achieved.Accepted author manuscriptTera-Hertz Sensin
The Transforming Dutch City seen through the Infrastructural Changes: Railways and the Case of Amsterdam
No full textThe relation between infrastructures and urban transformations is a complex matter. When we look at the Randstad, this part of the Netherlands is characterized by not only its urban development in the last 150 years, but also by the fact that the territory changed; herein geomorphology, waterways, and railroads play an important role. Since the Middle Ages, a well-developed system of canals is ordering landscape and cities, while roads had shallow relevance. Therefore, it is not a coincidence that the first Dutch railroads were positioned parallel to the canals. Land expropriation was easier there and the railway layout could be kept as straight as possible, saving resources.Theory, Territories & Transition

The study of urban form in the Netherlands
No full textThe study of urban form in the Netherlands has been heavily influenced by the Modern Movement and characterized by strong disciplinary specialization. On the one hand there is the distinction between art and engineering and on the other the search for instrumental universal rationality. This helps to explain the increasing interest, initially within academe, in the first English and German translations of some outstanding works of Italian researchers, who were at the time already acting as leaders in new perspectives in the fields of urban form and architecture. In keeping with the Dutch practical attitude, these investigations contributed to urban developments of the post-industrial era, beginning at the end of the 1970s. Today much of the study of urban form entails investigation of how global trends affect local systems and how local systems can be improved by analysing best practices. In that respect the Netherlands has been able to establish a leading role in contemporary architecture that is widely recognized within EuropeArchitectureArchitecture and The Built Environmen

Dissipation Losses in Artificial Dielectric Layers
No full textClosed-form expressions to describe artificial dielectric layers (ADLs) with finite conductivity are presented. The propagation of a generic plane wave within the artificial material is described by means of transmission line models, where each layer is represented as an equivalent shunt impedance. The given analytical formulas for the shunt impedance are derived assuming finite conductivity of the metal, thus also an accurate estimation of the losses within the artificial dielectric is obtained from the equivalent circuit. The expressions account for the reactive coupling between the layers due to higher order Floquet modes, thus remain valid even for extremely small electrical distance between layers.Accepted Author ManuscriptTera-Hertz Sensin
