A new adaptive baseband digital predistortion technique Emmanuel Cottais, Yide Wang and Serge Toutain Abstract -- This paper presents a new method intented to linearize power amplifiers with memory by adaptive baseband predistortion. This method is based on Hammerstein temporal model for the amplifier. Experimental results show that this technique can greatly attenuate intermodulation products and

38 GHz signal optical fiber transmission using guided-wave electro-optic single-sideband modulators with polarization reversals Hiroshi Murata', Kazumasa Kaneda', Akira Enokihara2 and Yasuyuki Okamura Abstract -- 38GHz optical single-sideband (SSB) modulation by using a new guided-wave electro-optic SSB modulator with polarization reversals was experimentally demonstrated and its applications to r

Transmission in rectangular waveguides periodically loaded with SRRs: simulation and measurement Carlos A. Fernandes', Ricardo Marqués2, Mario Silveirinha3 Abstract -- This paper revisits the topic of transmission in cut-off rectangular waveguides periodically loaded in the Eplane with Split-Ring Resonators (SRR), to present some new results and interpretations: it is shown that along with the kno

The early days of the European Microwave Conference André Vander Vorst, Peter J.B. Clarricoats A historical prospective on the establishment and purposes of the European Microwave Association, or EuMA, has been published in the Microwave Magazine, IEEE-MTT, in 2001 [1]. It shows that the story started with the foundation of the European Microwave Conference, EuMC, in 1969. The EuMC was first estab

Negative refraction and focusing using photonic crystal superlattice Yair Neve-Oz1, Michael Golosovsky1, Avraham Frenkel2, Dan Davidov1 Abstract -- We consider a planar periodic array of dielectric cylinders of two different diameters. This array forms a two-dimensional photonic crystal superlattice. The structural modulation results in a narrow passband inside the photonic stopband. For the frequ

Multiplicative measure of planar chirality for 2D meta-materials Serge P. Boruhovich1 Sergey L. Prosvirnin1, Alexander S. Schwanecke2, Nikolay I. Zheludev2 , Abstract -- We describe a new efficient continuous geometrical measure of two-dimensional chirality for photonic and microwave planar meta-materials. Its properties include integrability, scale-independence, boundedness to a well defined inte

Left-handed multilayer super compact coupled-line directional coupler Wei Tong, Zhirun Hu Abstract -- A super compact backward-wave directional coupler, composed of two multilayer left-handed transmission lines, is present. Compared to existing left-handed directional couplers, the proposed has much smaller size and broader bandwidth due to its much size-reduced multilayer unit cells. A quasi 0-dB

Highly-directive planar leaky-wave antennas: a comparison between metamaterial-based and conventional designs Giampiero Lovat l , Paolo Burghignoli2, Filippo Capolino3, David R. Jackson4 Abstract -- A comparative study is made of two types of planar leaky-wave antennas. The first type is a "conventional" planar leaky-wave antenna composed of a grounded slab that is covered with a metallic or diel

EUROPEAN MICROWAVE ASSOCIATION EuMA Guest Editorial Ferran Martin Metamaterials have experienced a significant advance in recent years in the field of Science, Engineering and Technology. Definition of the metamaterial concept is rather vague, and there is indeed some controversy concerning the type of structures or media included in the term. Probably, being relatively moderate and trying to fo

Experimental verification of left-handed characteristics of Split Ring Resonators and wires array in finline Aurélien Marteau, Eric Lheurette, Thibaut Decoopman, Xavier Mélique, Olivier Vanbésien, Didier Lippens Abstract -- We characterize experimentally the electromagnetic properties of a metamaterial-based transmission line periodically loaded by split ri ng resonators and wires in a finline tec
