Cylinders of elastic solids are widely used in various mechanical and electrical structures for many purposes including structural and functional elements. Vibrations of cylinders are of interests for the optimal design and enhanced performance through the consideration of structural and material parameters. By extending earlier work on free vibrations of an elastic cylinder based on the expansion...
In this paper, the electromagnetic energy harvesting scheme by using a Terfenol-D/PZT/Terfenol-D composite magnetoelectric (ME) transducer and a circuit is presented. In the experiments, the electrodes on the piezoelectric layer are connected by a circuit whose impedance is denoted by Z, which is the load impedance. we have analyzed and observed the load dependence of the ME coefficient and the basic...
In this study, low-profile planar triple symmetric arms dipole antenna is proposed for wireless communication applications. Three symmetric arms are etched on the metallic layer of a single sided printed circuit board to form the planar dipole antenna. The size parameters of symmetric arms are changed to design and fabricate the antenna which can be operated at 900/1800/2450 MHz successfully. We use...
