Three-Dimensional Comer Reflector Antenna
A reflector antenna utilizing three planar reflectors and a 3/4 X-unipole radiator is proposed. Calculations based on image and EMF-methods predict that the gain is about 5 dB greater than that of the two-dimensional comer reflector antenna, and that the input impedance is roughly between 50 and 75 9. Experiments conducted on the three-dimensional corner reflector antenna with rectangular comer...
متن کاملEnumeration of Varlet and Comer Hypergroups
In this paper, we study hypergroups determined by lattices introduced by Varlet and Comer, especially we enumerate Varlet and Comer hypergroups of orders less than 50 and 13, respectively. 1 Basic definitions and results An algebraic hyperstructure is a natural generalization of a classical algebraic structure. More precisely, an algebraic hyperstructure is a non-empty set H endowed with one or...
متن کاملBien cube, les données textuelles peuvent s'agréger !
Résumé. La masse des données aujourd’hui disponibles engendre des besoins croissants de méthodes décisionnelles adaptées aux données traitées. Ainsi, récemment de nouvelles approches fondées sur des cubes de textes sont apparues pour pouvoir analyser et extraire de la connaissance à partir de documents. L’originalité de ces cubes est d’étendre les approches traditionnelles des entrepôts et des ...
