## Abstract Artificial magnetic conductors (AMC) are proposed for the fabrication of subwavelength cavities in the microstrip technology. These metamaterials can simultaneously present a low phase value at reflection and a high impedance for normal incident waves over a wide frequency band. Planar

Abstract
In this article, the highly directive emission based on a new type of metamaterial has been demonstrated. A structure of crossed metallic strips with slots is designed. By embedding the source inside a slab of such material, the emitted energy is concentrated around the normal of the slab based on the zero refraction principle. An antenna is constructed, and the simulation has been done on it. The results show that highly directive property is achieved. An experimental verification of this effect is given in the microwave domain, and the results agree well with the simulations. Β© 2009 Wiley Periodicals, Inc.

In conclusion, we assembled three-dimensional structures of colloidal particles on a water surface rather than on a planar substrate. The ordered structure was obtained by evaporating the solvent at elevated temperature, and the resulting crystal was transferred onto a planar substrate by simple sed
K 2 In 12 Se 19 is a new ternary chalcogenide in the system K 2 Se-In 2 Se 3 (m.p. 997 K; colour: dark red) with the two components in a molar ratio of 1:6. This unusual solid shows a temperature-dependent order-disorder transition originating mainly from a dynamical disorder of In 3+ at elevated te
How do retaining glycosyltransferases function? To answer this question, UDP-Gal and galactose were covalently linked to form disubstrate analogues 1, of which surprisingly 1Ξ² and not 1Ξ± inhibited Ξ±(1-3)-galactosyltransferases very well. An understanding of this inhibition is a key to the pharmacolo
