Design of a narrow-band filter based on the Brewster phenomenon for microwave applications

2017

A high-efficiency narrow-band filter based on a Dielectric Frequency-Selective Surface (DFSS) has been predicted theoretically for oblique plane-wave incidence. A DFSS showing total reflection at a frequency of 10.5 GHz, based on the Brewster phenomenon for TM polarization, has been designed with a single dielectric grating, showing extremely low-reflectance sidebands adjacent to the resonance peak. The angular and spectral response of the designed filter has been studied. In addition, dielectric ohmic losses have been accounted for in this structure. This work was supported by the Agencia Estatal de Investigación (AEI) and by the Unión Europea through the Fondo Europeo de Desarrollo Region…

Comparing creative industries in Europe

2016

Creative industries are increasingly understood to contribute to localised innovation and dynamism. This paper provides a methodologically consistent comparison of creative industries across France, Great Britain, Italy and Spain. We map spatial agglomerations of creative activities showing evidence of urban concentration, which for Britain and France coincides with the dominance of capital cities, whilst for Spain and Italy, significant concentrations can also be found in secondary cities. The four countries also differ in the specialisation profiles and in the role played by policy makers. A lack of dove-tailing with the European Union smart agenda is argued to be a cause of concern.
