Existing studies on elastic waves in periodically laminated piezoelectric structures mainly concerned the passive band properties, since the electrical boundaries in the considered structures cannot vary. This paper investigates the tuning of band propert... see more

An important issue in antenna array design is reduction of mutual coupling. In square microstrip antennas this reduction can be achieved by using electromagnetic band-gap (EBG) structures. They can help in the reduction of mutual coupling by using their c... see more

The concept of frequency gaps in phononic crystals is widely used in physics. The feasibility and efficiency of applying this principle in damping out seismic and mechanical induced vibrations in real scale of civil engineering constructions are presented... see more

A wavelet-based finite element method (WFEM) is developed to calculate the elastic band structures of two-dimensional phononic crystals (2DPCs), which are composed of square lattices of solid cuboids in a solid matrix. In a unit cell, a new model of band-... see more

The aim of this study is to investigate the tablecloth behaviour of High Bandama basin for the best management of groundwater. It was based on satellite Landsat TM images and piezometric data acquired during three campaigns (August 2009, April 2010, and M... see more

A compact wide band reconfigurable bandpass filter (BPF) which utilises a hemi-circular flower shaped multimode resonator (MMR) is presented. The proposed MMR provides three resonant modes which fall within the broad frequency spectra. Among these, two mo... see more

In Côte d'Ivoire, the problem of access to drinking water is particularly acute because the impoundments built for supplying water to populations are no longer properly served and are subject to very strong eutrophication. Hence the use of groundwater. Th... see more

Longitudinal stability of the forearm is mainly provided by three structures: the radiocapitellar contact, which acts as the primary stabilizer, the central band of the interosseous ligamentous complex (IOLC) and the intact triangular fibrocartilage compl... see more
