Optimal Shape Control of Composite Thin Plates with Piezoelectric Actuators
Emerging technologies in microsensing, microactuation, active airfoils, turbine blades, and large, lightweight, flexible space structures can benefit from piezoelectric actuators for active shape control. Piezoelectric materials develop strain under applied voltage which induces structural deflection. This article presents analytical models, FEM solution, and optimal shape control of composite ...
متن کاملDouble-shell metamaterial coatings for plasmonic cloaking
The ideas of employing the unique properties of meta-materials and plasmonic media for cloaking and invisibility applications have been recently suggested and investigated by several groups [1–5], and they may find numerous applications in physics and technology. While many of the recent designs of the cloaking structures are based on the transformation optics and exact formulas [6], the origin...
متن کاملResolution composite shell with a layer of piezoelectric vibration analysis
In this paper, the vibration of composite cylindrical shell with piezoelectric layers in the interior and exterior surfaces is investigated. The composite shell without piezoelectric layers can be studied and compared the results with the results of other researchers, the cylindrical shell laminated with layers of piezoelectric vibration checked. The result is a three-dimensional elasticity equ...
متن کاملThin Absorbing Screens Using Metamaterial Surfaces
Metamaterial surfaces can be conceptualized by 2-dimensional periodic arrangement of many small flat inclusions on an otherwise homogeneous host surface. Electromagnetic properties of such metamaterial plates, which can indeed be regarded as frequency-selective surfaces, are influenced by the shape and geometry of these inclusions. When a metamaterial surface is closely placed above a perfectly...
متن کاملFabrication and characterization of a negative-refractive-index composite metamaterial
We have designed, produced, and experimentally characterized 2.7 mm thick composite panels having negative refractive index between 8.4 and 9.2 GHz. The composite metamaterial is fabricated using conventional commercial multilayer circuit-board lithography; three-dimensional physical (as opposed to electromagnetic) structure is introduced by the use of vias to form sections of the scattering el...
