Modal properties and radiative features of surface and leaky waves on metamaterial grounded slabs Lampariello1, Paolo Baccarelli', Paolo Burghignoli1, Fabrizio Frezza1, Alessandro Galli', Paolo Giampiero Lovat2 and Simone Paulotto1 Abstract -- In this paper a review of some recent results concerning guidance and radiation phenomena in a double-negative (DNG) metamaterial grounded slab is presented

Miniaturized dual-mode microstrip bandpass filters using meander space-filling curves Mohamed H. Awida, Amr M. E. Safwat and Hadia El-Hennawy Abstract -- A new class of dual-mode microstrip loop resonators is proposed and developed for the miniaturization of high selectivity narrowband microwave bandpass filters. The novelty of the proposed structures lies behind the efficient usage of the space i

Microwave characterization of materials in civil engineering Adriana Brancaccio', Francesco Soldovieri2 , Giovanni Leone', Domenico Sglavo' and Rocco Pierri' Abstract -- This paper deals with a free space method for the electromagnetic characterization of building materials at microwave frequencies. The technique exploits both transmission and reflection measurements and the experimental data is p

Highly linear low-voltage IQ downconverter for reconfigurable wireless receivers Krzysztof Dufrêne and Robert Weigel Abstract -- This paper describes design of an active, highlylinear, low-voltage IQ downconversion mixer based on a currentmode output architecture for use in cellular applications operating in a 700MHz - 2200MHz frequency range. Trade-offs between current consumption and performance

Green's theorem in electromagnetic field theory Karl F. Warnick1 and Peter Russer2 Abstract -- Green's theorems are commonly viewed as integral identities, but they can also be formulated within a more general operator theoretic framework. The radiation integral for fields in terms of a source and Green's function can be derived in this way. We show that Green's theorem can also be used to obtain

Experimental results of ground moving target detection achieved with the multi-channel SAR/MTI system PAMIR D. Cerutti-Maori, W. Bürger, J.H.G. Ender and A.R. Brenner Abstract -- The airborne experimental multichannel SAR/MTI system PAMIR (Phased Array Multifunctional Imaging Radar) has been designed and developed by FGAN-FHR in order to demonstrate some capabilities of future reconnaissance syste

EUROPEAN MICROWAVE ASSOCIATION EuM A Editorial More than one year has passed since the Inaugural Issue of the Proceedings of the European Microwave Association (Volume 1, Issue 1, March 2005) has been published. At the beginning of our second year we can state that booting up this new journal has been successful! This Proceedings is an archival, peer-reviewed journal apperaring four times per ye

Design of a millimeter-wave active integrated antenna using a global analysis Eric Marzolf and M'hamed Drissi Abstract-- An active integrated antenna operating in the millimeter band at 60 GHz is presented in this paper. A patch antenna and a low-noise amplifier are integrated on the same GaAs substrate, so as to be directly matched to each other and to remove all the bulky interconnections betwee

An injection-locked upconversion mixer Willem Laflere and Michiel Steyaert Abstract -- An efficient quadrature upconversion mixer is presented, able to drive --3 Min to a 50Q load or to the input of a PA. The system is operating in the UMTS-band with a bandwidth sufficient for UMTS-applications. The measured EVM of a demodulated test-signal is less than 3%. This is achieved using an oscillating dr

A review of sea wind vector retrievals by means of microwave remote sensing Maurizio Migliaccio1 and Antonio Reppucci2 Abstract -- Wind vector over the sea is fundamental to predict and understand meteorological and climatic processes. Microwave remote sensing is able to make measurements that can be processed to estimate the wind vector. This ensures a better spatial and temporal coverage with re
